HEAD DETECTION AND TRACKING SYSTEM
HDTS (Head detection and Tracking System) detects and tracks multiple people in a real time video stream in an efficient way. HDTS detects heads and faces in an outdoor and indoor environment and keeps track of them. HDTS uses Partial Head Contour method to detect head and Feature invariant methods to detect face. Head is located at an extreme position of the body and there is noticeable difference between the head and the shoulders in the input image. Face can be detected by finding the distance between eyes, colour intensity between eyes and other parts of the faces. HDTS is able to re-detect a person even if he/she is invisible for some time. People can become invisible if they wall behind pillars or walls. The principle in developing this system can be extended to solve other problems such as human gesture recognition and face recognition.
