Introduce some algorithms for real- time video motion detection in image sequences for surveillance .Itbring forward a quick way to getmain motion vectors of moving objects.A image difference algorithm which can suppress variable scene illumination is used to label the motion region.Perform an AND operation between the label image and the edge image,and get the edge points in the motion region. Then use the block match method to estimate motion vectors of the moving object.That way is used in digital video surveillance equipment.Itcan provide intelligentsurveillance and compress the store data. 图像处理 运动检测 边缘检测 块匹配 image processing motion detection edge detection block match 10.14188/j.1671-8836.2000.05.022 TN919.8 国家自然科学基金!（ 695 72 0 3 0 ）;武汉市科委重点项目资助!（ 9810 0 10 0 5 ） 2000-05-01 2021-04-01 5
