AI Virtual Zoom Using Gesture

This project implements a virtual zoom system using hand gestures, utilizing OpenCV and cvzone to track hand movements and zoom in/out based on distance between hands. The system detects hands in real-time and resizes an image dynamically based on gesture input.

Features

• Hand gesture-based zooming
• Real-time hand tracking using OpenCV and cvzone
• Smooth zooming effect with distance measurement
• Works with any webcam

Installation

1. Clone the Repository

git clone https://github.com/yourusername/AI-Virtual-Zoom-Gesture.git
cd AI-Virtual-Zoom-Gesture

2. Install Dependencies

Ensure you have Python installed, then run:

pip install opencv-python cvzone numpy

Usage

Run the script:

python AIVirtualZoomGesture.py

How It Works

1. Start the script → Webcam turns on.
2. Show both hands with index & middle fingers up → Zoom starts.
3. Move hands closer → Zooms in.
4. Move hands apart → Zooms out.
5. Release hands → Resets the zoom.

Code Explanation

• Hand tracking: Detects hands using cvzone.HandTrackingModule.
• Distance measurement: Calculates distance between hand centers.
• Dynamic image resizing: Resizes the image based on hand distance.

Troubleshooting

Issue	Solution
ModuleNotFoundError: No module named 'cvzone'	Run pip install cvzone
Webcam not detected	Check cv2.VideoCapture(0), try 1 if using an external webcam
Image not appearing	Ensure pikatchu.jpeg is in the correct directory

Future Improvements

• Add hand tracking smoothing for better accuracy.
• Implement single-hand zooming (e.g., thumb & index finger).
• Display zoom percentage for user feedback.
