[0038] Below in conjunction with accompanying drawing and specific implementation, the present invention is described in further detail:
[0039] refer to figure 1 , the implementation steps of this example are as follows:
[0040] Step 1, get the initial SAR image.
[0041] Obtain two registered SAR images I1 and I2 in different phases in the same area, such as figure 2shown.
[0042] refer to figure 2 (a), I1(i, j) represents the gray value of the pixel at position (i, j) in Figure I1.
[0043] refer to figure 2 (b), I2(i, j) represents the gray value of the pixel at position (i, j) in Figure I2.
[0044] Both images I1 and I2 have a size of 291×306, where 1≤i≤291, 1≤j≤306.
[0045] Step 2, obtain the labels for capsule network training according to the SAR experiment graph.
[0046] (2a) Calculate the similarity S(i,j) between pixels of the SAR experimental image:
[0047]
[0048] S(i,j) represents the similarity between pixels at the same position (i,j) of ...
