The prototype must process the video stream in real time, recognise the presence of a smartphone, then look for behavioural cues—hand placement, posture and, ideally, gaze direction—to confirm active usage. Whenever the model judges that the phone is being used, it should trigger an audible or visible alarm on the host machine instantly; no other logging or alert channels are required for this first iteration. I am happy for you to choose your preferred computer-vision stack (e.g. OpenCV, MediaPipe, PyTorch, TensorFlow, ONNX) as long as the end result runs on a typical workstation without specialise...

Project Title: Iraqi License Plate Detection and Recognition using Python (YOLO + OCR) Description: I am looking for a developer to build a complete Python project for automatic Iraqi vehicle license plate detection and recognition. Project Requirements: 1. Detect Iraqi license plates from vehicle images using a deep learning model (preferably YOLOv8). 2. Crop the detected license plate from the image. 3. Apply OCR to recognize the license plate number and characters. 4. The system should support Arabic letters, English letters, and Arabic-Indic numbers used in Iraqi license plates. 5. Use data augmentation techniques (rotation, blur, illumination changes) to improve model performance. 6. Provide training and testing scripts. 7. Provide the full Python source code. Tools preferr...
I’m building a proof-of-concept layer that intercepts any image or video delivered through a web browser and automatically replaces detected humans or animals with a neutral “shadow” placeholder. The aim is to strip away elements that might provoke irrational responses while keeping the surrounding media unchanged. Here’s what I need you to deliver: • A working browser-based solution (extension, local proxy, or another approach you propose) that processes both static images and streaming video in real time. • Reliable detection of people and animals using modern computer-vision tools (e.g., TensorFlow, OpenCV, YOLO, or alternatives) and seamless substitution with a non-identifying silhouette or blurred overlay. • A simple toggle UI so users can...

I’m building an MVP that inspects coal quality from both photos and short videos. The system must return a simple breakdown—e.g., “Coal 75 % / Stone 25 %”—and lay the groundwork for optional size-distribution analysis in later releases. What you’ll have to work with • A batch of truck-loading videos and corresponding lab quality reports. Phased scope Phase 1 – Extract still frames from the supplied videos and organise them into a clean, labelled image set. Phase 2 – Train a computer-vision model (YOLO or a comparable CNN in Python) able to distinguish coal from stone. Baseline accuracy is sufficient for now; we can iterate later. Both real-time and batch inference modes should be supported. Phase 3 – Wrap the model in...
We are looking for an experienced full-stack developer to build a scalable AI-powered web platform that provides multiple online image processing tools. The platform should allow users to upload images and process them using different tools such as background removal, image compression, upscaling, format conversion, and enhancement. The goal is to build a high-quality platform comparable to popular online image tools, with a focus on good performance, scalability, and search engine visibility. Core Tools (Phase 1): • Background remover • Image compressor • Image upscaler • Photo enhancer • PNG to JPG converter • JPG to PNG converter • Image resizer • Crop image tool • Background blur tool Processing Architecture: The platfo...
I need a small Windows-only application that can take a folder of 20–100 TIFF files, apply a unique pixel shift and crop to each image, then save the processed set to disk. After that, the program should average the processed images into a single composite frame and finally assemble every frame into a short video clip. All parameters—image size, batch size, per-file pixel shift, crop dimensions, output frame rate and any other relevant image settings—must be editable from a clean, graphical interface that carries my company logo. No multilingual support is required, so the UI can stay in English. To speed things up I can supply an existing Lua script that demonstrates the core image calculations; feel free to translate or rewrite it in the language you are most comforta...
OpenCV Hill Climb Project – Description Project Title: Autonomous Hill Climbing Robot using OpenCV Project Description: Developed an AI-based computer vision system using OpenCV and Python that enables a robot/vehicle to automatically detect and climb slopes or hills. The system processes real-time camera input to analyze terrain conditions such as slope direction, obstacles, and surface edges. Implemented image processing techniques like edge detection, contour detection, and gradient analysis to determine the steepest safe path for climbing. Applied the Hill Climbing optimization algorithm to continuously choose the best next movement direction based on terrain analysis. Integrated real-time decision making so the robot adjusts movement dynamically while climbing uneven surf...
Hello, I need a small program or automation script for the game Greedy Cat running on an Android emulator like LDPlayer or BlueStacks. Requirements: 1. The tool should monitor the game screen every round. 2. Detect the result icon (for example: tomato, carrot, fish, etc.). 3. Record each result with the round number and time. 4. Save the data automatically into a file (Excel or CSV). 5. The program should run continuously and record results all day. The game runs inside an Android emulator, so the tool should read the result from the screen using image recognition or screen detection. If possible, it should also show simple statistics like the last results and hot items. Please tell me: - Estimated cost - Time needed to build the tool. Program name in game xena
I want to build a small, self-contained charging station that wakes up only when it “sees” a bottle and a can. The core will be an Arduino (any recent 32-bit board is fine) tied to a solar panel and battery pack. A lightweight AI vision module or camera running something like TensorFlow Lite or OpenCV should continuously—or on a duty-cycled basis—look for bottles. The moment a bottle is detected, the system must move straight into the charging routine without waiting for external confirmation; no alerts, no logging, just automatic activation. What I need from you • Complete Arduino firmware that integrates the vision trigger with the charge-controller logic. • A schematic / wiring diagram showing how the camera, solar panel, charge controller, and any...
I have continuous video footage from live inspection of steel flat bars strips our production line and need a complete deep-learning pipeline that flags surface, structural, and functional defects in real time. The raw videos are already labeled by timestamp; frame-level annotation may still be required for optimal accuracy. Scope • Design and train a deep neural network—CNN, transformer, or hybrid model—that detects all three defect categories directly from video streams. • Implement preprocessing (frame extraction, augmentation, ROI isolation) and post-processing (tracking, alert generation) in Python using libraries such as PyTorch/TensorFlow and OpenCV. • Optimise for inference on an on-premise GPU; latency under 200 ms per frame is the target. &bull...
We need an Android developer to add iPhone-style panorama to the Open Camera app (open source: ). Goal: Implement panorama in Open Camera so it works like iPhone: guided on-screen motion, smooth horizontal panning, and one stitched panorama image. • Works seamlessly on both the front and back cameras. • Guides the user with the same arrow-line UI Apple uses, keeping motion smooth and level. • Captures a continuous series of frames, stitches them on-device, and outputs one high-quality image without pushing memory limits. You’ll work only against the official Open Camera codebase (or a clean fork you create). I’ll take your branch and merge it into our own app later.
