AI Painter is a fun and interactive project that lets you draw on your screen using your hands — no mouse, no stylus, just gestures.
It is built with OpenCV for computer vision and Mediapipe for real-time hand tracking.
- Detects your hand landmarks in real time using Mediapipe.
- Lets you select colors and tools (pen, eraser) by raising two fingers and tapping on the header bar.
- Draws on a virtual canvas when you raise your index finger (like a brush).
- Includes an eraser mode when the black color is selected.
- Merges your drawing with the live camera feed.
