Face tracking demo

This is a demo for detecting and tracking multiple faces in real time.
It uses the jsfeat CV library for the detection and the tracking.

Live Demo

How it works

• We start by running face detection algorithm on the current video frame.
• For each detected face, tracking points are randomly selected within the detected face region.
• We then track these points in the video using an optical flow algorithm, until a specified time interval has passed.
• We then run the detection algorithm again and match the freshly detected faces to the existing ones using a minimum distance approach.
• If a face was not re-detected, we prune it after several detection cycles.

Compatibility

This demo uses getUserMedia to access the camera feed and should work on all browsers except IE.
