Embodiment Construction
[0052] The method of texture extraction based on the shape-adaptive neighborhood gray level co-occurrence matrix will be further described below in conjunction with the accompanying drawings, but the embodiments of the present invention are not limited thereto.
[0053] The present invention is a remote sensing image processing method combining shape-adaptive neighborhood SAN and texture extraction, assuming: to obtain a group of multi-band images h, or high-resolution images g, if let SAN be an irregular polygon defined by its compressed image f area, for discrete digital images, SAN is a limited discrete grid, including the following steps:
[0054] 1) Image preprocessing ── Synthesize the multispectral image h with RGB color images in the image bands, and convert it to the HSV color space; or directly perform contrast enhancement on the high-resolution image g, such as: histogram equalization or segmented linear drawing Stretch and so on. Among them, in order to improve th...
