Volume Hand Controller

The Volume Hand Controller is a Python-based project that utilizes the cv2 (OpenCV) and mediapipe libraries to capture hand gestures in real-time via a webcam. The system detects the position of the thumb and index finger, and based on their distance, it adjusts the audio volume. This gesture-based control provides an intuitive, touch-free way to manage volume levels, offering a seamless integration of computer vision and gesture recognition.
