Embodiment Construction
[0039] The present invention will be further described below in conjunction with accompanying drawing:
[0040] refer to figure 1 , the implementation steps of the present invention are as follows:
[0041] Step 1, input two images, choose one as the reference image I 1 , take the other as the image to be registered I 2 .
[0042] The two input images are respectively intercepted from two SAR images of different phases acquired by an airborne radar in China.
[0043] Step 2, extract the feature points of the input image, and calculate the local descriptor similarity between the feature points of the reference image and the feature points of the image to be registered.
[0044] 2a) Using the scale-invariant feature transform SIFT method to extract the reference image I 1 and the image to be registered I 2 feature points, the I 1 and I 2 All feature points of are stored in sets R and S respectively;
[0045] 2b) Generate the feature point descriptor des of the reference...
