🧩 How It Works

1. Webcam Feed: Captures video using OpenCV.
2. Hand Detection: MediaPipe detects 21 hand landmarks.
3. Finger Tracking: Detects which fingers are up using custom logic.
4. Drawing Mode:
   • If only the index finger is up, it draws on the canvas.
   • If multiple fingers are up, drawing stops.
5. Canvas Merge: Blends live camera feed with your drawn strokes using cv2.addWeighted().

  Try restarting your computer or checking permissions.
• 🧱 mediapipe not found:
  Reinstall mediapipe using pip install mediapipe.
