[0056] In order to make the technical solutions and advantages of the present invention more clear, the technical solutions in the embodiments of the present invention are clearly and completely described below in conjunction with the drawings in the embodiments of the present invention:
[0057] Such as figure 1 A hyperspectral image classification method based on spatial feature iteration is shown, and the specific steps are as follows:
[0058] Known hyperspectral image data r=(r 1 ,r 2 ,...r n ) T , where n is the number of pixels in the hyperspectral image, r i (1≤i≤n) indicates the i-th pixel of the hyperspectral image, r i =(r i1 ,r i2 ,...r iL ), where L represents the number of bands of the hyperspectral image.
[0059] Concrete implementation steps of the present invention are as follows:
[0060] A. Assume that the signal source of the known hyperspectral image pixel includes the object D, the background part U and the interference signal I, and each objec...
