Embodiment Construction
[0048] In order to make the technical means, creative features, achievement goals and effects realized by the present invention easy to understand, the present invention will be further described below with reference to the specific embodiments.
[0049] like figure 1 As shown, first collect continuous image frames in the surveillance video; for each pixel gray value, adjust the weights of different gray values by sampling the time difference between it and the historical frame, gray difference and duration and other information to achieve Model the background, and restore a more accurate background model; divide the image into blocks, use the regional feature invariance of the image block to extract the foreground area, and eliminate some dynamic interference, and then judge the illumination change of the foreground area. , in order to determine whether it is necessary to make a secondary judgment of the foreground area through the improved texture features; the accurate ex...
