Embodiment 1
[0048] Embodiment 1: The semi-supervised hyperspectral remote sensing image classification method based on information entropy is the same as the steps of the above-mentioned specific implementation; figure 2 (a) is the hyperspectral remote sensing original image that the present invention uses, and it is the image on March 23rd, 1996 of Florida Kennedy Space Center (KSC) that the airborne imaging spectrometer AVIRIS of National Aeronautics and Space Administration (NASA) obtains, There are a total of 224 bands, the spectral range is 400-2500, the spectral resolution is 10nm, and the spatial resolution is 18m. For the data in the study area, the effects of water vapor absorption and low SNR bands are removed, and a total of 120 bands are selected for analysis. The training data is selected according to the images provided by the Landsat Thematic Mapper (Landsat Thematic Mapper). According to the interpretation of the images, the land cover in this area is divided into 13 major...
