Salient motion information detection technique using weighted subtraction image and motion vector

Moving object detection is very important for video surveillance in modern days. In special case, we can categorize motions into two types- salient and non-salient motion. In this paper, we first calculate temporal difference image for extract moving objects and adapt to dynamic environments and next, we also propose a new algorithm to detect salient motion information in complex environment by combining temporal difference image and binary block image which is calculated by motion vector using the newest MPEG-4 and EPZS.
