Day 110/365 — Building a Hand Detection System with Python Today I started working on a real-time hand detection system using my webcam. The goal? To move closer to building AI-powered gesture control systems (think controlling apps with your hands ). 🛠️ What I’m using: - Python – core language - OpenCV – for camera capture & image processing - MediaPipe – for hand tracking & detection-Webcam (real-time input) What I built today: - Connected camera using OpenCV - Displayed live video feed - Set up the loop to process frames - Preparing for hand landmark detection next What’s next: 1. Detect hand landmarks 2. Track finger positions 3. Map gestures to actions (like volume control, scrolling, etc.) This is how simple projects grow into powerful AI systems. #Day109 #365DaysOfCode #Python #AI #ComputerVision #OpenCV #MediaPipe #BuildInPublic #ZambiaTech

Previously, I explored computer vision with Python 👁️🐍, building projects to better understand how machines perceive and interpret visual data. One such project involved developing a real-time color detection system using OpenCV 🎯. The application tracks a selected color through a live webcam feed 📷 and highlights it with bounding boxes in real time, demonstrating how machines can isolate and follow visual patterns dynamically. While working on this project, I focused on: • 🎨 Converting color spaces from BGR → HSV for more robust detection • ⚙️ Designing dynamic color thresholds for adaptability • 🧩 Applying masking techniques to isolate specific regions • 🎥 Handling real-time video streams efficiently This project was a hands-on step into bridging theory with real-world visual intelligence 🧠, and it opened the door to deeper explorations in computer vision. More projects from that journey coming soon — stay tuned 🚀✨ 🔗 GitHub Repository: https://lnkd.in/gJ6BjTwH #ComputerVision #Python #OpenCV #MachineLearning #AI #DeepLearning #ImageProcessing #TechProjects #CodingJourney #DeveloperLife #BuildInPublic #LearnByDoing #PortfolioProject #Innovation

Excited to share one of my computer vision projects: Eye Detection / Drowsiness Monitoring System 👁️💻 Built a real-time system that detects eye activity using a webcam feed to monitor blink patterns and eye closure behavior. 🔧 Tech Stack: • Python • OpenCV • MediaPipe • Pygame (for alert system) 🚀 Key Features: • Real-time eye landmark detection • Eye open/closed state tracking • Drowsiness alert triggering • Low-latency live performance This project uses EAR (Eye aspect ratio) calculation, takes the input measurements from the webcam via the eye landmarks, calculates them compares it to the given threshold value and gives the output. Always interesting to see how simple vision signals can turn into impactful applications.
