[0043] The attached drawings are only for illustrative purposes, and cannot be understood as a limitation of the patent;
[0044] In order to better illustrate this embodiment, some parts of the drawings may be omitted, enlarged or reduced, and do not represent the size of the actual product;
[0045] For those skilled in the art, it is understandable that some well-known structures in the drawings and their descriptions may be omitted.
[0046] The technical scheme of the present invention will be further described below in conjunction with the drawings and embodiments.
[0047] This embodiment provides a hyperspectral classification method based on attention-constrained non-negative matrix factorization, which specifically includes the following steps:
[0048] S1: First read a hyperspectral image, the number of known categories is r, and the hyperspectral image matrix X=[x 1 ,...,x m ] T ∈R m×n ; X is an m-dimensional matrix.
[0049] Among them, m represents the number of bands of th...
