In video sequences,it generally exists that some parts of moving object overlap between different frames,such as bend,jumping-in-place,waving hands and so on.Thus,the overlapped parts are often taken as background wrongly.In order to improve the integrality of moving objects,an algorithm based on background subtraction and edge extraction is proposed.At first,the combination of adaptive median filter(AMF) and mean filtering was used to extract the cleaner background,and the general location of m...
