Embodiment Construction
[0035] The technical solutions of the present invention will be further described below in conjunction with the accompanying drawings and embodiments.
[0036] Such as figure 1 Shown is the flow chart of the method of the present invention. A method for automatic registration of multi-source remote sensing images based on J-divergence, the specific steps are as follows:
[0037] (S1) Using the spatial variation model to perform spatial transformation on the image to be registered;
[0038] (S2) Calculate the J-divergence of the overlapping part of the transformed image to be registered and the reference image, where each calculated J-divergence is equivalent to the objective function value corresponding to a set of spatial transformation parameters in the transformed space; the specific steps yes:
[0039] (S21) extracting the joint histogram of the overlapping parts of the transformed image to be registered and the reference image;
[0040] (S22) Calculate the edge densit...
