[0038] refer to figure 1 , the specific embodiment of the present invention is as follows:
[0039] Step 1. Input image, matrix and regularization parameters.
[0040] (1a) Input the low spatial resolution hyperspectral image L∈R respectively h×w×B and a high spatial resolution multispectral image Y ∈ R H×W×b , h and w are the height and width of the low spatial resolution hyperspectral image, B is the band number of the low resolution hyperspectral image, H and W are the height and width of the high spatial resolution multispectral image, b is the high spatial resolution The number of bands in the multispectral image;
[0041] In the embodiment of the present invention, low spatial resolution hyperspectral and high spatial resolution multispectral images taken in the Washington area are used. The size of the low spatial resolution hyperspectral image is 64×64×191, and the high spatial resolution Panchromatic image size is 256×256×6.
