Abstract


In this paper, we propose an efficient real time moving object detection algorithm on video sequences obtained from a stationary camera. It is based on motion estimation and compensation using block-matching algorithm to detect a moving objet. It consists of the following steps: the first consists to estimate the motion vectors between successive frames using Diamond search algorithm. In the second step, the blocks that had motion vector in the frames are compensated with the white pixels value and those with zero motion that is the stationary are compensated by black pixels value. In the third step, the morphological opening and closing filters are used for refining the object detected. Real video sequences were used for object detection with utilization our algorithm. A set of experimental results is presented in the paper.
