Embodiment Construction
[0076] First, detect the moving target in the satellite video, using the method based on motion and local clutter modeling, the specific implementation method is as follows:
[0077] Step 1: In each frame, divide the image into two-dimensional grids along the vertical and horizontal directions, and each grid unit contains several pixels;
[0078] Step 2: The image is regarded as the sum of the original image signal and the noise signal, and an exponential distribution is selected to fit the distribution of the noise signal;
[0079] Step 3: Find the area with large grayscale changes as the target, and set the false alarm rate to 1×10 in advance. -2 , calculate the threshold value of binarization, and use this threshold value to classify the pixels, that is: the pixel amplitude value greater than the threshold value is the foreground, anyway it is the background (in the binary image, '1' is the foreground, '0' is the background) ;
[0080] Step 4: Take the intersection map of...
