Hyperspectral image wave band selection method, system, equipment and medium

The invention belongs to the technical field of spectral data classification, and discloses a hyperspectral image waveband selection method, system and device and a medium. The hyperspectral image waveband selection method comprises the steps of obtaining a multi-scale similar graph matrix based on a hyperspectral image to be subjected to waveband selection; fusing the obtained multi-scale similar graph matrixes to obtain a fused similar graph matrix; substituting the obtained fused similar graph matrix into an edge graph self-representation model to obtain a multi-scale edge enhanced graph self-representation model; solving the obtained multi-scale edge enhanced graph self-representation model, and obtaining an importance-based wave band sequence; and obtaining a hyperspectral image waveband selection result based on the waveband sorting. According to the method, the accuracy, robustness and generalization performance of hyperspectral image waveband selection can be effectively improved, the situation of wro
