Embodiment Construction
[0014] The present invention will be further described below in conjunction with the accompanying drawings and embodiments, and the present invention includes but not limited to the following embodiments.
[0015] Such as figure 1 As shown, a hyperspectral image band selection method based on global optimal clustering of the present invention, its implementation steps are as follows:
[0016] Step 1: Normalization processing, that is, according to p n =(p o -M 2 ) / (M 1 -M 2 ) to normalize the hyperspectral image, where, p n is the pixel value of the normalized image, p o is the pixel value of the original hyperspectral image, M 1 is the maximum value of the pixel value in the original hyperspectral image, M 2 is the minimum value of the pixel value in the original hyperspectral image;
[0017] Step 2: According to the physical meaning of the hyperspectral image, that is, adjacent bands have greater similarity, and the bands in a cluster should be continuous. According...
