Hand Gesture Drawing App

This project implements a real-time hand gesture drawing application using OpenCV, MediaPipe, and Python. The application allows users to draw on a virtual canvas by using their hand gestures detected through a webcam.

Features

• Drawing with Index Finger: When your index finger is raised, you can draw on the canvas.
• Clear Canvas: When all fingers are raised (gesture for all fingers open), the canvas gets cleared.
• Change Color: Use the 'A' and 'D' keys to change the color of the brush.
• Change Brush Size: Use the 'W' key to increase the brush size and 'S' to decrease it.
• Real-time Drawing: Draw freely with smooth brush strokes that follow the position of your index finger.

Requirements

• Python 3.x
• OpenCV
• Mediapipe
• Numpy

Installation

Install the required dependencies:

pip install opencv-python mediapipe numpy

How to Use

1. Open the terminal and run the main script:

   python Drawing.py
   

2. The webcam feed will open up, and you can interact with the virtual canvas using hand gestures.

   • Drawing: Raise your index finger to start drawing.
   • Clear Canvas: Raise all your fingers to clear the canvas.
   • Change Color: Press 'A' to switch to the previous color and 'D' to switch to the next color.
   • Change Brush Size: Press 'W' to increase the brush size and 'S' to decrease it.

3. Press ESC to exit the application.

Customization

• You can modify the colors, brush size limits, and detection/tracking confidence in the code to fit your preferences.
• The project uses a fixed canvas size (800x600), but this can be changed if desired.

Acknowledgements

• This project utilizes MediaPipe for hand tracking, which provides real-time hand gesture recognition.
• OpenCV is used for capturing video input and drawing on the canvas.
