Building Hand Detection System with Python and OpenCV

Built my first Real-Time AI Hand Gesture Recognition System Today I built a computer vision project using Python, OpenCV, and MediaPipe that can detect a human hand in real-time through webcam and count fingers accurately. 🧠 Features: ✔ Real-time hand tracking ✔ Finger counting (0–5) ✔ Gesture recognition (STOP / GO) ✔ Hand orientation fix (left/right detection) This project helped me understand how AI models process live camera input and how small logic changes can significantly improve accuracy (especially thumb detection based on hand orientation). Tech Stack: Python | OpenCV | MediaPipe Still learning, but step by step building toward real-world AI applications and computer vision systems. Next goal: upgrading this into a full gesture-controlled system (mouse control / volume control). #MachineLearning #ComputerVision #Python #AI #OpenCV #LearningByDoing #100DaysOfCode

Been exploring Computer Vision using OpenCV and honestly had a lot of fun with it. Real-time hand tracking, gesture recognition, and object detection — all running live through the camera. Fed it custom image datasets so the model could learn and predict objects more accurately. Exploring how training data, model predictions, and real-time inference come together in practice. Still figuring out a lot and enjoying every bit of it. #OpenCV #ComputerVision #MachineLearning #Python #Ai #pythonprogramming
