Abstract
An object tracking system includes a foreground identifying module, an object grouping module, and an object tracking module. The foreground identifying module determines an attribute information of each pixel position of a current processing frame according to a difference between a pixel value of each pixel position of the current processing frame and that of a background model frame, so as to generate a current foreground frame. The object grouping module sets a label to each pixel position according to the attribute information of surrounding pixel positions of each pixel position, and connects adjacent pixel positions with the same label to form an object. The object tracking module determines the object being a tracked object according to whether the pixel positions corresponding to the object are at least partially overlapped with the pixel positions corresponding to the tracked object.
