Professional Video & Photo Editing App Applied	~6 - 16 USD	20 hours ago	Client Rank - not enough data -
The goal is to create a professional-grade mobile application that places robust video editing, advanced photo retouching, and ready-to-use template creation under one roof. This tool is meant for commercial use, so the interface must feel polished and intuitive while still offering the depth that power users expect. Core feature set • Video editing – multi-track timeline, trim, crop, speed controls, transitions, key-frameable filters, and export up to 4K (FFmpeg or equivalent back-end is fine). • Photo editing – layer support, curves, HSL adjustment, AI-powered background remover, and batch export. OpenCV, GPUImage, or similar libraries are acceptable. • Template creation – users should be able to start from preset layouts, swap assets, tweak fonts/colors, and save custom templates for future use. Platform & tech Native Android (Kotlin) or a high-performance cross-platform stack such as Flutter or React Native is acceptable as long as real-time previews remain fluid on mid-range devices. Timeframe A complete, tested build (along with commented source code) is required within one month. Deliverables 1. Installable release build(s) 2. Full source code and build instructions 3. Brief user guide or in-app onboarding screens 4. One revision cycle after initial hand-off for polishing minor issues Acceptance criteria • All three feature groups work without crashing on Android 10+ devices. • Exported media matches selected resolution and quality settings. • UI elements scale correctly on both phone and tablet layouts. If you already have experience integrating FFmpeg, OpenCV, or similar SDKs into mobile projects and can comfortably meet the four-week deadline, this project should be a smooth fit.

Python Video Pipeline Stabilization (OpenCV / FFmpeg) Overview I have an existing Python-based video pipeline that generates videos from image + audio. The system is partially working, but unstable. Your task is to stabilize it — NOT to redesign or rebuild it. Current Pipeline photo → remove_background → (optional scene) → avatar video (from image) → audio (TTS or uploaded) → merge audio + video → final_video.mp4 Problem The pipeline sometimes: crashes returns invalid outputs breaks on edge cases Your Task Stabilize the pipeline so that: ✔ it NEVER crashes ✔ it ALWAYS returns a valid final_video.mp4 ✔ all steps respect input/output contracts Requirements You MUST: Ensure all functions return valid outputs: avatar → .mp4 ONLY audio → .mp3 ONLY final → .mp4 Implement fallback logic: if scene fails → use original photo if avatar fails → fallback to image-based video if audio fails → generate silent audio if merge fails → still return video Fix ALL crash points: no unhandled exceptions no None returns no invalid file formats Important Rules ❌ Do NOT rewrite architecture ❌ Do NOT add new features ❌ Do NOT change pipeline order ✔ Only fix and stabilize existing system Deliverables You must demonstrate: photo only → works photo + scene → works photo + audio → works photo + scene + audio → works In ALL cases: ✔ final_video.mp4 is generated ✔ no crashes Final Goal The system must be fully stable and ready for further development. This is a debugging + stabilization task, not a new build. To Apply Start your proposal with: "I understand pipeline stability requirements" So I know you read this.

Computer Vision Engineer (HUD Parser) Applied	$400	2 days ago	Client Rank - Medium Payment method verified Phone number verified $440 total spent 11 hires, 1 active 31 jobs posted 35% hire rate, 3 open job 5.00 /hr avg hourly rate paid 1 hours paid 5.00 of 4 reviews Industry: Tech & IT Company size: 2 Registered: Mar 1, 2025 United Kingdom London 00:47 3
We are seeking an expert Computer Vision Engineer to develop a HUD Parser using Python, RT-DETR, and ONNX. The project involves parsing HUD elements from video frames in real-time, with a focus on accuracy and efficiency. The ideal candidate will have experience in real-time object detection and image processing. The system ingests a video feed, runs CV over the in-game HUD, and emits JSON events that feed our backend. Think of it as a reader: the HUD already displays the score, timer, and round result for the players — we just need to read it programmatically, at scale, in real time. The stack is defined and non-negotiable: Python 3.11, RT-DETR or YOLOX (Apache 2.0 only — no Ultralytics), PaddleOCR PP-OCRv4, OpenCV, ONNX Runtime for inference, FastAPI, Pydantic. Ultralytics, Tesseract, and PyTorch in production paths are banned. The architecture is already designed and documented. A labelling tool and frame extractor will be ready before you start. You will receive working tooling, ~500 confirmed human-labelled frames, and remote access to a Mac Studio M3 Ultra (512 GB unified memory). Scope You own the ML-to-production loop for our first title — a 1v1 fighting game with a clean, symmetric HUD. This is the cleanest CV target in competitive esports: fixed layout, deterministic round structure, no mode fragmentation. 1. ROI calibration and training pipeline setup Validate that the region-of-interest definitions produce clean crops for all nine HUD elements (health bars, win indicators, timer, round banners). Adjust ROIs if needed using the calibration UI built into the labelling tool. 2. Train and evaluate the detector Train an RT-DETR (or YOLOX) model to detect and classify HUD elements across our confirmed label set. Target: ≥95% accuracy on held-out footage from typical broadcast conditions (streamer overlays, varied lighting). Export to ONNX. Every accuracy run must be logged to an append-only eval file — no exceptions. 3. Active learning loop Build the active learning pipeline: model auto-labels new frames, surfaces low-confidence frames to the labelling queue, humans confirm. Must run on the Mac Studio without cloud dependency. 4. Wire into the real-time pipeline Connect the trained ONNX model into the live video ingestion pipeline. The frame extraction layer is already built. You are connecting the detection and state machine layers so the system runs end-to-end against a live feed. 5. Shadow mode validation Run the live pipeline against three reference recordings with hand-annotated ground truth. Log every event emitted, compare against ground truth, fix discrepancies. Targets: ≥99% accuracy on clean broadcast footage, ≥95% on footage with streamer overlays and production graphics. Deliverables Production-ready ONNX weights for the first title Append-only eval log with ≥3 runs, each with a note describing what changed Wired, runnable real-time pipeline Working active learning loop script Short handoff doc: what you trained on, what you'd do next, open risks What we need from you Autonomous. Architecture is documented. One round of clarifying questions, then you execute. You own the ML decisions. Fast. Clean output. Type hints throughout, Pydantic schemas, pytest-backed eval scripts, concise commit messages. Honest on blockers. If label quality is insufficient or ROI calibration is off, flag it on day one. About the project Early stage, fast-moving. You report directly to the founder. Updates framed as outcomes and risks — not implementation detail. Remote, async-first. Compute provided: Mac Studio M3 Ultra (512 GB), cloud GPU credit for training runs exceeding local capacity. Client's questions: 1. What's your approach to training a HUD element detector when you have ~500 labelled frames and the target classes are highly imbalanced (e.g. "KO banner" appears in 2% of frames)? You're running inference at 2fps on a Mac Studio M3 Ultra. The OCR step is your bottleneck — PaddleOCR is taking 180ms per frame. What do you do? Your shadow mode run shows 97% accuracy overall but the model keeps missing one specific event. How do you diagnose whether it's a labelling problem, an ROI problem, or a model problem?

ZERØ FOD is an aerospace-grade, high-compliance tool control and digital inventory platform. We do not build consumer apps; we build liability-mitigating enterprise infrastructure for flight lines, heavy manufacturing plants, and industrial vendors. Our core technology uses an autonomous computer vision pipeline to ingest physical tool silhouettes via a mathematical calibration mat, dynamically generating millimeter-accurate 2D vectors. These vectors act as a "Digital Twin" to route custom CNC tool-control foam, while our software ledger tracks the chain-of-custody for millions of dollars in physical assets. In this environment, "move fast and break things" is not a virtue. If our system fails, an aircraft is grounded, or a line goes down. We require engineers who build with precision, paranoia, and strict adherence to protocol. [ OPERATIONAL DIRECTIVES ] As a core engineer on the ZERØ FOD matrix, your primary directives will include: Optical Pipeline Optimization: Refine and scale our Python/OpenCV ingestion engine. You will handle perspective transforms (homography), sub-millimeter scale calibration, and edge detection to generate perfect DXF/SVG geometry from mobile uploads. Ledger Integrity: Architect and harden the backend database mapping physical assets to their digital twins. You will build auditable, tamper-proof state machines for tool statuses ([ SECURED ], [ DEPLOYED ], [ OUT OF SERVICE ]). Frontend Execution: Deploy brutalist, hyper-legible, zero-latency React interfaces for Commander dashboards and shop-floor mobile web views. Enterprise Integration: Build secure APIs to handshake with billion-dollar VMI (Vendor-Managed Inventory) procurement systems for automated tool replacement and PO generation. [ TECHNOLOGY MATRIX ] You will operate within the following stack: Core Backend: Typescript, Python, OpenCV (Computer Vision), PostgreSQL Vector Mathematics: Computational geometry (translating pixel matrices to real-world metric CNC toolpaths). Frontend: React, Tailwind CSS (Strict UI constraints: zero border-radius, high contrast, dark mode only). Infrastructure: GCP, Docker, strictly typed API architecture. [REQUIREMENTS] Experience: 4+ years shipping production-grade software in high-stakes environments (fintech, aerospace, medical, or complex B2B SaaS). Domain Expertise: Deep understanding of Typescript, Python and computer vision fundamentals. You know why a fraction of a calibration square warps a homography matrix. Systems Thinking: You can map out complex physical-to-digital data flows. You understand that software doesn't exist in a vacuum; it exists in the hands of a mechanic wearing grease-covered gloves. Execution Style: You favor ruthless simplicity and reliability over over-engineered abstractions. Client's questions: A mechanic photographs a reflective chrome wrench under harsh hangar lighting. Briefly explain your OpenCV pipeline to handle glare/shadows and extract a millimeter-accurate contour for a CNC router path. A supervisor on desktop and a mechanic on spotty mobile Wi-Fi both try to change a tool's status to [SECURED] simultaneously. How do you architect the PostgreSQL state machine to guarantee strict ledger integrity? We build brutalist UIs for mechanics in grease-covered gloves. Tell me about an interface you built where absolute reliability trumped aesthetics. What abstractions did you strip out to make it bulletproof?

Senior iOS Computer Vision Engineer (AVFoundation, Real-Time Camera) Applied	$90 - $150 / hr	3 days ago	Client Rank - Good Payment method verified Phone number verified $3 592 total spent 1 hires 1 jobs posted 100% hire rate, 1 open job 35.00 /hr avg hourly rate paid 97 hours paid no reviews Industry: Food & Beverage Company size: 2 Registered: Feb 19, 2026 United States Houston 18:47 4
We are building a camera-first iOS product that acts as a real-time food decision system, not a typical mobile app or AI wrapper. The app opens directly into a live camera, identifies a single relevant target, holds a stable visual lock, evaluates whether the current view provides enough reliable proof, and then returns one clear action, a better-view request, or stays silent. The system is built around strict constraints: one focus, one move, no UI clutter, and no premature or low-confidence outputs. This requires deep experience with native iOS, AVFoundation, real-time camera pipelines, computer vision, and low-latency system design. We will begin with a short paid discovery phase to validate the architecture, technical feasibility, and prototype plan before committing to a focused prototype build. Client's questions: Describe a real-time iOS camera app you have built using AVFoundation. What did the camera pipeline do? How do you avoid sending every camera frame to a model? Describe your frame selection strategy. How would you implement a stable target lock and prevent jitter or lock thrashing? How would you determine if a camera view is reliable enough (e.g., blur, glare, occlusion, instability) before triggering any output? At a high level, how would you structure the pipeline from camera input to final user output (including when to stay silent)?

Dual AI Safety & Quality Monitors Applied	$25 - $50 / hr	3 days ago	Client Rank - not enough data -
I’m ready to commission two computer-vision solutions that share one codebase where possible yet ship as separate, production-ready applications. 1) PPE non-compliance detector • Desktop deployment only, packaged with Qt for a clean cross-platform GUI. • Live video or recorded footage should flag workers wearing a T-shirt, shorts, long sleeves without a vest, or simply no hardhat at all. False positives must stay low enough that a site supervisor can leave the model running unattended for hours. • The UI needs start/stop controls, confidence thresholds the user can tweak, and an overlay that boxes each infraction in real time. We’ll log every event with a time-stamp and frame grab to a local database or CSV so safety teams can review incidents later. 2) Rotten-fruit classifier • Separate desktop build, same Qt look and feel. • Target classes: fresh vs. rotten bananas and apples. Capture from webcam or load images in batch, then output “keep” or “discard” plus a confidence score. • Accuracy must be good enough for back-of-store triage, ideally above 90 % on a held-out test set we’ll supply. Deliverables • Source code (Python/C++ with OpenCV, PyTorch or TensorFlow—whichever gets the best inference speed on CPU). • Trained model files and a short document explaining architecture, training data, and how to fine-tune. • Installer or portable build for Windows; Linux support is a nice bonus. • Quick demo video showing both tools running on sample footage. I’ll provide sample datasets and will be available for fast feedback. Once the first prototype meets the accuracy targets we can discuss edge-case tuning and optional GPU acceleration.

We are seeking a skilled Algorithm Engineer (mid to senior level) on a contract or freelance basis to optimize an existing SIFT/SURF-based computer vision pipeline by identifying and resolving performance bottlenecks. The role involves profiling code using tools like gprof, Valgrind, or Intel VTune, benchmarking execution times, analyzing algorithm complexity, and implementing parallel processing techniques to accelerate feature extraction and matching, particularly for large images. The candidate will be responsible for reducing redundant computations, improving memory management, enhancing overall algorithm efficiency, and leveraging optimized libraries such as OpenCV. Strong proficiency in C/C++ or Python, solid experience with computer vision algorithms (especially SIFT/SURF), and knowledge of performance optimization and parallel computing are required, while experience with GPU acceleration (CUDA/OpenCL) is a plus. Deliverables include an optimized pipeline with measurable improvements, detailed profiling reports, and clean, well-documented code, along with continuous testing and iteration throughout the optimization process.

AI Event Bib Detection Upgrade Applied	~35 - 293 USD	4 days ago	Client Rank - not enough data -
I need an experienced computer-vision developer to step into an existing codebase and finish a real-time bib detection system for mass-participation sporting events. The current prototype already recognises bib numbers; your task is to stabilise it and expand the feature set so it can handle marathons, cycling races, triathlons—essentially any event where athletes wear start numbers. Core goals • Strengthen and optimise real-time detection accuracy under changing light, motion blur and camera angles. • Automate the creation of short clips that isolate each participant’s key moments. • Overlay a configurable sponsor logo on every generated clip. • Add seamless WhatsApp integration so the system can push the personalised clips straight to athletes or organisers. • Clean up, document and hand over the code so the next developer—or I—can maintain it easily. Tech context The previous developer used Python with OpenCV and a YOLO-style model; feel free to refactor or swap frameworks as long as inference remains lightning fast. Expect video streams up to 4K, multiple concurrent cameras and fairly busy backgrounds. Success criteria • ≥95 % accurate bib recognition measured on my test footage. • Clip creation and logo overlay processed within 30 s of finish-line crossing. • One-click WhatsApp delivery functioning from both desktop and mobile. • Well-commented code, README and deployment script. If you have proven experience in real-time computer vision, OCR, and messaging API integration, let’s talk. Skills: Python, Matlab and Mathematica, Machine Learning (ML), C++ Programming, Arduino, OpenCV, Computer Vision, YOLO Fixed budget: 30 - 250 EUR 4 days ago Websites, IT & Software, Engineering & Science, Python, C++ Programming, OpenCV, Computer Vision, Editing, Matlab and Mathematica, Machine Learning (ML), Arduino, YOLO Open project
Python Sports Tracking Engineer / 2D Football Replay Prototype (SkillCorner + mplsoccer) Applied	not specified	4 days ago	Client Rank - Medium Payment method verified 12 jobs posted 2 open job no reviews Registered: Aug 30, 2015 United Kingdom 01:47 3
I’m looking for a Python engineer / technical freelancer to help build a football data MVP. The goal is to take open SkillCorner tracking data from one A-League match and turn it into a clean 2D full-match replay, in the style of Football Manager’s classic 2D mode. This is a proof of concept, not a full commercial product yet. The role is primarily data/engineering-led, but ideally I’d like someone who can also handle the core visualisation layer using mplsoccer + Matplotlib, so that I don’t need a separate visualisation contractor for the first MVP. What the project involves The input data is frame-by-frame football tracking data containing player and ball positions from a real match. The output should be: a cleaned and animation-ready match timeline mapped correctly onto a top-down football pitch rendered as a basic but polished 2D replay video Scope of work For one selected SkillCorner A-League match, I need someone to: 1. Parse and prepare the data - load and interpret the SkillCorner match files - work with player and ball tracking data - handle frame-based x/y coordinates - map the data to football match time / match clock 2. Clean the movement data - smooth noisy movement - interpolate from the source data to a more watchable output at 10fps (frames per second) and 30fps in stages - stabilise player identities where possible - handle ball movement separately where needed - prepare a reliable animation-ready timeline 3. Build the replay layer Using mplsoccer + Matplotlib or another sensible Python-based approach: - draw the football pitch - plot player and ball locations over time - add team colours / circular player icons - place player numbers inside the circular icons - show player names as labels/popups where appropriate (i.e. when they're near/receiving or in control of the ball) and readable - add a match clock - ideally support possession-based / on-ball player labels if reliable 4. Custom pitch / visual style Ideally, I’d like the person to be able to upload a custom pitch graphic for the pitch design: - use mplsoccer for the football coordinate system - apply a custom pitch/background design underneath using Matplotlib/image assets - plot the player and ball locations on top of that custom pitch/background Even for the MVP, the aim should be high artistic and visual output but it should feel clean, watchable, and visually strong. 5. Export output - create a short test clip first - then create one full-match replay export - deliver either MP4 and the cleaned frame pipeline used to generate it Technical requirements Strong preference for someone with experience in: Python Pandas and/or Polars JSON / JSONL / CSV / time-series data interpolation / smoothing / trajectory cleanup Matplotlib mplsoccer sports tracking data or coordinate-based animation video export / animation workflows Nice to have football analytics experience familiarity with SkillCorner-style tracking data OpenCV sports data visualisation ability to make the replay readable on both larger screens and smaller screens ability to work independently without heavy design support Deliverables At minimum, I’d like: a short proof clip using a sample passage of play a cleaned full-match animation-ready timeline one full-match 2D replay export clear notes on the pipeline / assumptions used Important note This is not a live product and not a coaching/performance analysis tool. This is an entertainment / fan engagement MVP, so I care more about: a believable movement a beautiful visual output a compelling replay experience than about perfect analytical precision. Ideal candidate Ideally this is one person who can combine: data wrangling Python engineering tracking-data cleanup basic football plotting / visualisation If you’ve worked on football tracking, sports visualisation, motion from x/y coordinates, or anything similar, please share examples..

Core feature set
• Video editing – multi-track timeline, trim, crop, speed controls, transitions, key-frameable filters, and export up to 4K (FFmpeg or equivalent back-end is fine).
• Photo editing – layer support, curves, HSL adjustment, AI-powered background remover, and batch export. OpenCV, GPUImage, or similar libraries are acceptable.
• Template creation – users should be able to start from preset layouts, swap assets, tweak fonts/colors, and save custom templates for future use.

Platform & tech
Native Android (Kotlin) or a high-performance cross-platform stack such as Flutter or React Native is acceptable as long as real-time previews remain fluid on mid-range devices.

Timeframe
A complete, tested build (along with commented source code) is required within one month.

Deliverables
1. Installable release build(s)
2. Full source code and build instructions
3. Brief user guide or in-app onboarding screens
4. One revision cycle after initial hand-off for polishing minor issues

Acceptance criteria
• All three feature groups work without crashing on Android 10+ devices.
• Exported media matches selected resolution and quality settings.
• UI elements scale correctly on both phone and tablet layouts.

If you already have experience integrating FFmpeg, OpenCV, or similar SDKs into mobile projects and can comfortably meet the four-week deadline, this project should be a smooth fit.

Python Video Pipeline Stabilization (OpenCV / FFmpeg)
Overview
I have an existing Python-based video pipeline that generates videos from image + audio.

The system is partially working, but unstable.
Your task is to stabilize it — NOT to redesign or rebuild it.

Current Pipeline
photo → remove_background
→ (optional scene)
→ avatar video (from image)
→ audio (TTS or uploaded)
→ merge audio + video
→ final_video.mp4

Problem
The pipeline sometimes:

crashes

returns invalid outputs

breaks on edge cases

Your Task
Stabilize the pipeline so that:

✔ it NEVER crashes
✔ it ALWAYS returns a valid final_video.mp4
✔ all steps respect input/output contracts

Requirements
You MUST:

Ensure all functions return valid outputs:

avatar → .mp4 ONLY

audio → .mp3 ONLY

final → .mp4

Implement fallback logic:

if scene fails → use original photo

if avatar fails → fallback to image-based video

if audio fails → generate silent audio

if merge fails → still return video

Fix ALL crash points:

no unhandled exceptions

no None returns

no invalid file formats

Important Rules
❌ Do NOT rewrite architecture
❌ Do NOT add new features
❌ Do NOT change pipeline order

✔ Only fix and stabilize existing system

Deliverables
You must demonstrate:

photo only → works

photo + scene → works

photo + audio → works

photo + scene + audio → works

In ALL cases:
✔ final_video.mp4 is generated
✔ no crashes

Final Goal
The system must be fully stable and ready for further development.

This is a debugging + stabilization task, not a new build.

To Apply
Start your proposal with:

"I understand pipeline stability requirements"

So I know you read this.

Open project

Project: Pixie Smart Camera + App Prototype

Objective:
We are developing a smart camera system (Pixie) that behaves like a virtual camera operator.

We are looking for a developer (or small team) to:

1. Build and refine the React Native Android application

2. Integrate real-time video processing (tracking + auto zoom)

3. Assist in sourcing or building a suitable prototype camera system

This prototype will be used for investor demonstrations and product validation.

We already have working prototype logic that:

Performs real-time subject tracking

Applies smooth, natural auto zoom (PID-style motion)

Seamlessly transitions between face tracking and body tracking

Your role is to bring this to life in a stable, real-time system.

Core Requirements

1. Video Pipeline:
* Input: RTSP stream from Wi-Fi camera
* Real-time decoding and frame processing on Android
* Low-latency performance (target <200ms)

Notes:
* Processing can be done at 1080p / 2.7K
* 4K is desirable for output quality, not required for processing

2. Application Development (React Native + Native Modules)

You will:
* Integrate RTSP video into the app
* Pass frames to processing layer (native if needed)
* Render processed output (tracking + auto zoom)
* Build a simple but functional UI for testing.

Important:
You may need to use native Android (Java/Kotlin/C++) for performance-critical parts

3. Tracking & Auto Zoom Integration:
We already have:
* Working tracking + auto zoom logic (prototype stage)

You will:
* Integrate and optimise this for real-time performance
* Ensure smooth, stable behaviour
* Maintain low latency

4. Connectivity Architecture (IMPORTANT):
We are not using AP-mode cameras.

Required setup:
* Camera operates in Wi-Fi STA mode
* Camera connects to:
* either a router OR preferably a tablet hotspot (self-contained system)
* App and camera communicate over local network (LAN)

Streaming:
* RTSP (primary)
* WebRTC optional (bonus)

5. Camera (NEW REQUIREMENT):
* We are currently sourcing the correct camera hardware.
* We are looking for someone who can also assist with one of the following:

Option A (Preferred):
* Recommend and source a suitable off-the-shelf camera with:
* STA mode
* RTSP stream
* Low latency

Option B:
* Build a prototype camera system, for example:
* embedded Linux (e.g. Raspberry Pi or similar)
* custom RTSP/WebRTC pipeline

This is not mandatory, but a strong advantage

6. Power Requirements:
* Battery-powered preferred
* USB-C charging
* For prototype: external battery acceptable

Deliverables:
* Working Android app (React Native + native components)
* RTSP video successfully integrated
* Real-time tracking + auto zoom functioning
* Stable low-latency performance
* Camera integrated and working with the system

Basic documentation:
* setup instructions
* system architecture

Success Criteria:
* Smooth, natural tracking behaviour
* Stable auto zoom
* Low-latency live video
* Reliable connection between camera and app
* System suitable for investor demo

Important Notes:
* We do not currently have a final camera solution
* Previous camera tested (AP mode) is not suitable
* Flexibility and problem-solving are critical

Ideal Candidate:
* Strong experience with:
* React Native
* Android native development
* real-time video (RTSP/WebRTC)

Experience with:
* OpenCV / computer vision
* streaming pipelines
* embedded systems (bonus)

Open project

We are seeking an expert Computer Vision Engineer to develop a HUD Parser using Python, RT-DETR, and ONNX. The project involves parsing HUD elements from video frames in real-time, with a focus on accuracy and efficiency. The ideal candidate will have experience in real-time object detection and image processing.

The system ingests a video feed, runs CV over the in-game HUD, and emits JSON events that feed our backend. Think of it as a reader: the HUD already displays the score, timer, and round result for the players — we just need to read it programmatically, at scale, in real time.
The stack is defined and non-negotiable: Python 3.11, RT-DETR or YOLOX (Apache 2.0 only — no Ultralytics), PaddleOCR PP-OCRv4, OpenCV, ONNX Runtime for inference, FastAPI, Pydantic. Ultralytics, Tesseract, and PyTorch in production paths are banned.
The architecture is already designed and documented. A labelling tool and frame extractor will be ready before you start. You will receive working tooling, ~500 confirmed human-labelled frames, and remote access to a Mac Studio M3 Ultra (512 GB unified memory).

Scope
You own the ML-to-production loop for our first title — a 1v1 fighting game with a clean, symmetric HUD. This is the cleanest CV target in competitive esports: fixed layout, deterministic round structure, no mode fragmentation.
1. ROI calibration and training pipeline setup
Validate that the region-of-interest definitions produce clean crops for all nine HUD elements (health bars, win indicators, timer, round banners). Adjust ROIs if needed using the calibration UI built into the labelling tool.
2. Train and evaluate the detector
Train an RT-DETR (or YOLOX) model to detect and classify HUD elements across our confirmed label set. Target: ≥95% accuracy on held-out footage from typical broadcast conditions (streamer overlays, varied lighting). Export to ONNX. Every accuracy run must be logged to an append-only eval file — no exceptions.
3. Active learning loop
Build the active learning pipeline: model auto-labels new frames, surfaces low-confidence frames to the labelling queue, humans confirm. Must run on the Mac Studio without cloud dependency.
4. Wire into the real-time pipeline
Connect the trained ONNX model into the live video ingestion pipeline. The frame extraction layer is already built. You are connecting the detection and state machine layers so the system runs end-to-end against a live feed.
5. Shadow mode validation
Run the live pipeline against three reference recordings with hand-annotated ground truth. Log every event emitted, compare against ground truth, fix discrepancies. Targets: ≥99% accuracy on clean broadcast footage, ≥95% on footage with streamer overlays and production graphics.

Deliverables

Production-ready ONNX weights for the first title
Append-only eval log with ≥3 runs, each with a note describing what changed
Wired, runnable real-time pipeline
Working active learning loop script
Short handoff doc: what you trained on, what you'd do next, open risks

What we need from you

Autonomous. Architecture is documented. One round of clarifying questions, then you execute. You own the ML decisions.
Fast.
Clean output. Type hints throughout, Pydantic schemas, pytest-backed eval scripts, concise commit messages.
Honest on blockers. If label quality is insufficient or ROI calibration is off, flag it on day one.

About the project

Early stage, fast-moving. You report directly to the founder.
Updates framed as outcomes and risks — not implementation detail.
Remote, async-first.
Compute provided: Mac Studio M3 Ultra (512 GB), cloud GPU credit for training runs exceeding local capacity.

Client's questions:

1. What's your approach to training a HUD element detector when you have ~500 labelled frames and the target classes are highly imbalanced (e.g. "KO banner" appears in 2% of frames)?
You're running inference at 2fps on a Mac Studio M3 Ultra. The OCR step is your bottleneck — PaddleOCR is taking 180ms per frame. What do you do?
Your shadow mode run shows 97% accuracy overall but the model keeps missing one specific event. How do you diagnose whether it's a labelling problem, an ROI problem, or a model problem?
Describe your recent experience with similar projects

Data Science & Analytics, AI & Machine Learning

Open project

ZERØ FOD is an aerospace-grade, high-compliance tool control and digital inventory platform. We do not build consumer apps; we build liability-mitigating enterprise infrastructure for flight lines, heavy manufacturing plants, and industrial vendors.

Our core technology uses an autonomous computer vision pipeline to ingest physical tool silhouettes via a mathematical calibration mat, dynamically generating millimeter-accurate 2D vectors. These vectors act as a "Digital Twin" to route custom CNC tool-control foam, while our software ledger tracks the chain-of-custody for millions of dollars in physical assets.

In this environment, "move fast and break things" is not a virtue. If our system fails, an aircraft is grounded, or a line goes down. We require engineers who build with precision, paranoia, and strict adherence to protocol.

[ OPERATIONAL DIRECTIVES ]
As a core engineer on the ZERØ FOD matrix, your primary directives will include:

Optical Pipeline Optimization: Refine and scale our Python/OpenCV ingestion engine. You will handle perspective transforms (homography), sub-millimeter scale calibration, and edge detection to generate perfect DXF/SVG geometry from mobile uploads.

Ledger Integrity: Architect and harden the backend database mapping physical assets to their digital twins. You will build auditable, tamper-proof state machines for tool statuses ([ SECURED ], [ DEPLOYED ], [ OUT OF SERVICE ]).

Frontend Execution: Deploy brutalist, hyper-legible, zero-latency React interfaces for Commander dashboards and shop-floor mobile web views.

Enterprise Integration: Build secure APIs to handshake with billion-dollar VMI (Vendor-Managed Inventory) procurement systems for automated tool replacement and PO generation.

[ TECHNOLOGY MATRIX ]
You will operate within the following stack:

Core Backend: Typescript, Python, OpenCV (Computer Vision), PostgreSQL

Vector Mathematics: Computational geometry (translating pixel matrices to real-world metric CNC toolpaths).

Frontend: React, Tailwind CSS (Strict UI constraints: zero border-radius, high contrast, dark mode only).

Infrastructure: GCP, Docker, strictly typed API architecture.

[REQUIREMENTS]
Experience: 4+ years shipping production-grade software in high-stakes environments (fintech, aerospace, medical, or complex B2B SaaS).

Domain Expertise: Deep understanding of Typescript, Python and computer vision fundamentals. You know why a fraction of a calibration square warps a homography matrix.

Systems Thinking: You can map out complex physical-to-digital data flows. You understand that software doesn't exist in a vacuum; it exists in the hands of a mechanic wearing grease-covered gloves.

Execution Style: You favor ruthless simplicity and reliability over over-engineered abstractions.

Client's questions:

A mechanic photographs a reflective chrome wrench under harsh hangar lighting. Briefly explain your OpenCV pipeline to handle glare/shadows and extract a millimeter-accurate contour for a CNC router path.
A supervisor on desktop and a mechanic on spotty mobile Wi-Fi both try to change a tool's status to [SECURED] simultaneously. How do you architect the PostgreSQL state machine to guarantee strict ledger integrity?
We build brutalist UIs for mechanics in grease-covered gloves. Tell me about an interface you built where absolute reliability trumped aesthetics. What abstractions did you strip out to make it bulletproof?

Web, Mobile & Software Dev, Web Development

Open project

We are building a camera-first iOS product that acts as a real-time food decision system, not a typical mobile app or AI wrapper. The app opens directly into a live camera, identifies a single relevant target, holds a stable visual lock, evaluates whether the current view provides enough reliable proof, and then returns one clear action, a better-view request, or stays silent. The system is built around strict constraints: one focus, one move, no UI clutter, and no premature or low-confidence outputs. This requires deep experience with native iOS, AVFoundation, real-time camera pipelines, computer vision, and low-latency system design. We will begin with a short paid discovery phase to validate the architecture, technical feasibility, and prototype plan before committing to a focused prototype build.

Client's questions:

Describe a real-time iOS camera app you have built using AVFoundation. What did the camera pipeline do?
How do you avoid sending every camera frame to a model? Describe your frame selection strategy.
How would you implement a stable target lock and prevent jitter or lock thrashing?
How would you determine if a camera view is reliable enough (e.g., blur, glare, occlusion, instability) before triggering any output?
At a high level, how would you structure the pipeline from camera input to final user output (including when to stay silent)?

Hourly rate:

Open project

I’m ready to commission two computer-vision solutions that share one codebase where possible yet ship as separate, production-ready applications.

1) PPE non-compliance detector
• Desktop deployment only, packaged with Qt for a clean cross-platform GUI.
• Live video or recorded footage should flag workers wearing a T-shirt, shorts, long sleeves without a vest, or simply no hardhat at all. False positives must stay low enough that a site supervisor can leave the model running unattended for hours.
• The UI needs start/stop controls, confidence thresholds the user can tweak, and an overlay that boxes each infraction in real time. We’ll log every event with a time-stamp and frame grab to a local database or CSV so safety teams can review incidents later.

2) Rotten-fruit classifier
• Separate desktop build, same Qt look and feel.
• Target classes: fresh vs. rotten bananas and apples. Capture from webcam or load images in batch, then output “keep” or “discard” plus a confidence score.
• Accuracy must be good enough for back-of-store triage, ideally above 90 % on a held-out test set we’ll supply.

Deliverables
• Source code (Python/C++ with OpenCV, PyTorch or TensorFlow—whichever gets the best inference speed on CPU).
• Trained model files and a short document explaining architecture, training data, and how to fine-tune.
• Installer or portable build for Windows; Linux support is a nice bonus.
• Quick demo video showing both tools running on sample footage.

I’ll provide sample datasets and will be available for fast feedback. Once the first prototype meets the accuracy targets we can discuss edge-case tuning and optional GPU acceleration.

Open project

We are seeking a skilled Algorithm Engineer (mid to senior level) on a contract or freelance basis to optimize an existing SIFT/SURF-based computer vision pipeline by identifying and resolving performance bottlenecks. The role involves profiling code using tools like gprof, Valgrind, or Intel VTune, benchmarking execution times, analyzing algorithm complexity, and implementing parallel processing techniques to accelerate feature extraction and matching, particularly for large images. The candidate will be responsible for reducing redundant computations, improving memory management, enhancing overall algorithm efficiency, and leveraging optimized libraries such as OpenCV. Strong proficiency in C/C++ or Python, solid experience with computer vision algorithms (especially SIFT/SURF), and knowledge of performance optimization and parallel computing are required, while experience with GPU acceleration (CUDA/OpenCL) is a plus. Deliverables include an optimized pipeline with measurable improvements, detailed profiling reports, and clean, well-documented code, along with continuous testing and iteration throughout the optimization process.

I need an experienced computer-vision developer to step into an existing codebase and finish a real-time bib detection system for mass-participation sporting events. The current prototype already recognises bib numbers; your task is to stabilise it and expand the feature set so it can handle marathons, cycling races, triathlons—essentially any event where athletes wear start numbers.

Core goals
• Strengthen and optimise real-time detection accuracy under changing light, motion blur and camera angles.
• Automate the creation of short clips that isolate each participant’s key moments.
• Overlay a configurable sponsor logo on every generated clip.
• Add seamless WhatsApp integration so the system can push the personalised clips straight to athletes or organisers.
• Clean up, document and hand over the code so the next developer—or I—can maintain it easily.

Tech context
The previous developer used Python with OpenCV and a YOLO-style model; feel free to refactor or swap frameworks as long as inference remains lightning fast. Expect video streams up to 4K, multiple concurrent cameras and fairly busy backgrounds.

Success criteria
• ≥95 % accurate bib recognition measured on my test footage.
• Clip creation and logo overlay processed within 30 s of finish-line crossing.
• One-click WhatsApp delivery functioning from both desktop and mobile.
• Well-commented code, README and deployment script.

If you have proven experience in real-time computer vision, OCR, and messaging API integration, let’s talk.

Open project

I’m looking for a Python engineer / technical freelancer to help build a football data MVP.

The goal is to take open SkillCorner tracking data from one A-League match and turn it into a clean 2D full-match replay, in the style of Football Manager’s classic 2D mode.

This is a proof of concept, not a full commercial product yet.

The role is primarily data/engineering-led, but ideally I’d like someone who can also handle the core visualisation layer using mplsoccer + Matplotlib, so that I don’t need a separate visualisation contractor for the first MVP.

What the project involves

The input data is frame-by-frame football tracking data containing player and ball positions from a real match.

The output should be:

a cleaned and animation-ready match timeline
mapped correctly onto a top-down football pitch
rendered as a basic but polished 2D replay video

Scope of work

For one selected SkillCorner A-League match, I need someone to:

1. Parse and prepare the data
- load and interpret the SkillCorner match files
- work with player and ball tracking data
- handle frame-based x/y coordinates
- map the data to football match time / match clock

2. Clean the movement data
- smooth noisy movement
- interpolate from the source data to a more watchable output at 10fps (frames per second) and 30fps in stages
- stabilise player identities where possible
- handle ball movement separately where needed
- prepare a reliable animation-ready timeline

3. Build the replay layer

Using mplsoccer + Matplotlib or another sensible Python-based approach:

- draw the football pitch
- plot player and ball locations over time
- add team colours / circular player icons
- place player numbers inside the circular icons
- show player names as labels/popups where appropriate (i.e. when they're near/receiving or in control of the ball) and readable
- add a match clock
- ideally support possession-based / on-ball player labels if reliable

4. Custom pitch / visual style

Ideally, I’d like the person to be able to upload a custom pitch graphic for the pitch design:

- use mplsoccer for the football coordinate system
- apply a custom pitch/background design underneath using Matplotlib/image assets
- plot the player and ball locations on top of that custom pitch/background

Even for the MVP, the aim should be high artistic and visual output but it should feel clean, watchable, and visually strong.

5. Export output
- create a short test clip first
- then create one full-match replay export
- deliver either MP4 and the cleaned frame pipeline used to generate it

Technical requirements

Strong preference for someone with experience in:

Python
Pandas and/or Polars
JSON / JSONL / CSV / time-series data
interpolation / smoothing / trajectory cleanup
Matplotlib
mplsoccer
sports tracking data or coordinate-based animation
video export / animation workflows

Nice to have
football analytics experience
familiarity with SkillCorner-style tracking data
OpenCV
sports data visualisation
ability to make the replay readable on both larger screens and smaller screens
ability to work independently without heavy design support

Deliverables

At minimum, I’d like:

a short proof clip using a sample passage of play
a cleaned full-match animation-ready timeline
one full-match 2D replay export
clear notes on the pipeline / assumptions used
Important note

This is not a live product and not a coaching/performance analysis tool.

This is an entertainment / fan engagement MVP, so I care more about:

a believable movement
a beautiful visual output
a compelling replay experience

than about perfect analytical precision.

Ideal candidate

Ideally this is one person who can combine:

data wrangling
Python engineering
tracking-data cleanup
basic football plotting / visualisation

If you’ve worked on football tracking, sports visualisation, motion from x/y coordinates, or anything similar, please share examples..

Computer Vision Developer – Automatic Tracking of Pallet Movement from Video

Project Description

We are looking for an experienced computer vision developer to build a system that automatically tracks the movement of a pallet during a load stability test using video recordings.

The goal is to replace an existing manual tracking solution (10+ years old) with a modern, robust, and automated system.

⸻

Scope of Work

The system must:

* Import and process video files
* Automatically detect and track 3 visual points (markers) on a pallet
* Track movement frame-by-frame
* Work reliably with:
* low to medium video quality
* reflections from stretch film
* Calculate:
* angular deviation from vertical (90° reference)
* lateral displacement (mm or pixels)
* maximum movement during the test
* Output:
* processed video with overlay (tracking points + reference line)
* data export (CSV or similar)
* simple visualization (movement over time)

⸻

Technical Requirements

* Strong experience with OpenCV
* Background in computer vision / image processing
* Experience with:
* object tracking (optical flow, feature tracking, blob detection, etc.)
* handling noisy or low-quality video
* Preferred:
* Python or C++
* experience with industrial measurement systems

⸻

Important Notes

* We are open to using ArUco markers or similar visual markers
* The developer should evaluate what gives the most stable and reliable tracking
* The first prototype should compare:
* tracking using natural/simple visual points
* tracking using ArUco markers
* Camera position is fixed
* Lighting conditions and reflections may vary

⸻

Deliverables

* Working prototype
* Source code
* Clear usage instructions
* Optional: simple user interface (a plus, not required)

⸻
