Moving object detection is a useful tool for such purposes as intelligent video browsing/analysis and video surveillance systems. Previously several algorithms have been reported on moving object detection from compressed video data. However, in these algorithms, flat regions are often falsely detected. In addition if multiple moving objects are involved, each moving object may not be identified and therefore object tracking becomes very difficult. We describe a fast moving detection and identification method from MPEG coded data. The experimental results show that each moving object is successfully identified for several surveillance sequences.
