nodejs-mediapipe

This project integrates MediaPipe Solutions with Node.js and Express for real-time computer vision tasks. It showcases examples of image segmentation, hand and face detection, and pose detection, with a combined example for all three types of landmark detection.

Utilizing MediaPipe's client-side JavaScript APIs, the project performs video processing directly in the browser, minimizing server-side computation. Additionally, it features logging for hand and face gestures, tracking interactions both in the console and a text file in the server logs directory.
