Real-time zoom-in & zoom-out using hand gestures through Computer Vision

About this app

This computer-vision app will visually read the human hand gestures from any video or Web-CAM in real-time & then able to translate it to zoom-in or zoom-out of that video streaming. This application developed using Open-CV & another brilliant model calls Mediapipe. This project is for the intermediate Python developer & Data Science Newbi's.
