What is tracking.js and how is it different to openCV?

Tracking.js is a lightweight JavaScript library designed for real-time object tracking and face detection in web applications. Unlike OpenCV, which is a comprehensive computer vision library with advanced capabilities, Tracking.js focuses on simplicity and runs entirely in the browser without requiring additional installations or plugins. Tracking.js is ideal for basic tasks like color tracking, face detection, and custom object recognition, but it lacks the extensive feature set and deep learning integration of OpenCV. OpenCV, on the other hand, is more versatile and supports a wide range of platforms, including desktop, mobile, and embedded systems, making it suitable for complex applications.
