Visual analysis of human movement is a hot topic in the field of computer vision. A novel algorithm- column integral, speed up the head location, and has the more precision than previous algorithm. A head turning detection algorithm has been presented, which based on the color information of each space branch area and template match, and it is simple and effective. The experiment result indicate that...
A new background updating algorithm of timely replacement of a central regional background was presented in this paper aiming at the PTZ camera video surveillance scenes. Before the object moving out of the setting field, the camera was static and the background subtraction algorithm was used to detect the moving object. Once the object moving out of the setting field, the camera which was controlled...
