Embodiment Construction
[0029] The specific embodiments of the present invention will be described below in conjunction with the accompanying drawings.
[0030] Such as figure 1 As shown, the present invention discloses an improved hyperspectral image classification method for hyperspectral image processing, the specific steps are as follows:
[0031] Step 1, selection of spatial neighbors of pixels in the center of the image: the spatial features in the spectral-space joint classification under the spatial preprocessing mode are the basic guarantee for the final high-quality classification, and the spatial features depend on the selection of spatial neighbors. The present invention focuses on mining and utilizing spatial information to Obtain spatial information features that can better describe the central pixel, and focus on efficiency and accuracy to meet actual needs, paving the way for step 2.
[0032] Step 2, extract the spatial features of the central pixel: Through step 1, the high-quality ...
