Real-time Face Tracking using TensorFlow.js

		Takes live video stream from webcam and creates facemesh
		(facial feature-map) by capturing 468 facial landmark points

		To run using .mp4 video file, simply add
		<source src="VIDEO_PATH" type="video/mp4">
		tag inside <video> </video> in HTML

		and comment out live_webcam() function call..

		Body Segmentation using TensorFlow.JS Body-Pix model

		Takes live video stream from web camera, and runs
		segmentation using Body-Pix model from TensorFlow.JS

		Identifies animal species in Wild-Life documentary films using
		Mobile-Net Image Classification model in TensorFlow.JS

		https://github.com/tensorflow/tfjs-models/tree/master/mobilenet

		Sample video : wild-life.mp4

		Marks Bounding Boxes around the Objects detected in the video using
		TensorFlow.JS COCO-SSD model..

		Builds a KNN Classifier for Sports Activity Recognition using
		Transfer Learning on a pre-trained model Mobile-Net

		Link to KNN Classifier in TensorFlow.JS :

		https://github.com/tensorflow/tfjs-models/tree/master/knn-classifier

		Activity Recognition can be performed in 3 simple steps:

		1. Compile training video which demonstrates various sports activities
		that you want to capture automatically using Machine Learning

		2. For each activity, capture few screenshots from the training video
		and tag them manually to train the knn-classifier

		3. Run predictions using the knn-classifier

		Extracts person from an input video stream using Body-Pix model in
		TensorFlow.JS and replaces the video backdrop

		Sample background images are provided in this directory 'backdrop-k.jpg'.
