Embodiment Construction
[0037] refer to figure 1 , the specific implementation process of the present invention is as follows:
[0038] Step 1. Input the SAR image Y to be speckle-reduced, and use the variance map method to divide the image Y into a smooth area pixel set Y ΩS and edge region pixel set Y ΩE , to get the smooth marker matrix S Y and edge labeling matrix E Y .
[0039] (1a) Let the pixel of the SAR image Y to be speckle reduced be expressed as y(i, j), and define each pixel of the variance map as:
[0040] V ( i , j ) = Σ m , n ∈ W [ y ( i , j ) - y ( m ...
