Moving object detection

Moving object detection can be realized simply. Frame difference method [18] is also called time difference method. It detects moving objects by comparing the gray values of the pixels corresponding to the current frame and adjacent frames in the video sequence image, and then finds the difference, In video sequence images, there is continuity between adjacent images. When there is a moving object in the video image, due to the motion of the moving object, the gray value difference of pixels between adjacent images will be larger. On the contrary, when there is no moving object in the video image, the gray value difference of pixels between adjacent images will be smaller. The frame difference method takes advantage of this feature of video image It is the simplest method of moving object detection. The frame difference method is to use two adjacent frames to do the difference operation, and then do the binary processing, so as to detect the moving target.
