🎨 Virtual Drawing Board — OpenCV + MediaPipe Project

Draw anything on the screen with your index finger — no stylus, no touchscreen, just your webcam and your hand! ✍️🖐️
This real-time gesture-based drawing app is powered by MediaPipe and OpenCV using hand landmarks and finger detection.

🖼 Demo

🧠 How It Works

🖐️ This project uses your webcam to detect hand gestures and switches between drawing and selection modes based on finger positions:

• ☝️ Only Index Finger Up → Drawing Mode
• ✌️ Index + Middle Finger Up → Selection Mode (choose color or eraser)
• ✋ All 5 Fingers Up → Clear the entire drawing board

You can toggle between different colors and an eraser by moving your fingers to the top toolbar area.
