Embodiment Construction
[0043] figure 1 It is a flow chart of the present invention, below in conjunction with a specific embodiment, a kind of video image space moving target detection method based on motion information of the present invention is described in further detail, and its specific steps are as follows:
[0044] Step 1: Given the original image f(x,y,t);
[0045] Using a video image captured by a satellite in orbit for the experiment, the image size is 871×527, the gray level is 8bit, and 20 consecutive frames of images are processed. figure 2 for frame 9.
[0046] Step 2: denoise the image by mean filtering;
[0047] The calculation method of the mean filtering is:
[0048] g ( x , y ) = w ( x , y ) * f ( x , y ) ...
