Hand Tracking Air Canvas

This project captures live webcam input and translates specific hand gestures into drawing actions on an OpenCV-backed canvas. It leverages MediaPipe Hands to detect finger positions and lets you draw, erase, or pick colors using intuitive gesture controls.

Requirements

• Python 3.8 or newer
• Webcam access
• Install the required packages with:

  pip install opencv-python mediapipe numpy

How to run

1. Make sure the webcam is available and installed drivers are functional.
2. From the project directory, execute:

   python app.py

3. The window titled "Air Canvas" will appear. Use the following gestures:
   • Open palm (thumb + all fingers): clears the canvas.
   • Index finger only: draw on the canvas.
   • Index + middle fingers: pick a color from the on-screen palette.
4. Press q to exit and release the webcam.
