Embodiment Construction
[0033] The specific implementation steps of the low-rank sparse representation-based hyperspectral image suspicious target detection method provided by the present invention will be described in detail below with reference to the accompanying drawings. Such as figure 1 As shown, for the hyperspectral image, the suspicious target detection and location are performed through the following steps in turn:
[0034] (1) Read in the hyperspectral image data cube and related projection parameters.
[0035] First, read in the hyperspectral image in TIFF or HDR format through the GDAL library function, and then read the projection parameters and geographic coordinate conversion parameters in the hyperspectral image into the memory, and use it after detecting suspicious targets. Then load the hyperspectral image cube into the memory, and finally arrange n pixels in the entire image in the form of rows or columns in the image plane space to form a d×n matrix, where d is the number of hyp...
