Matrix pattern waveband selecting method based on spectrum information divergence

The invention belongs to the technical field of remote sensing image processing, and relates to a matrix pattern waveband selecting method based on spectrum information divergence. The matrix pattern waveband selecting method includes the steps of acquiring high-spectral remote sensing images and calculating discrete coefficient of each wave band of the images, and spectrum information divergence between various wavebands, calculating information divergence matrix factors based on the discrete coefficient of each wave band and spectrum information divergence between various wavebands, calculating single wave band index of each wave band based on the information divergence matrix factors, and selecting optimal wave band combination from large to small based on the single wave band indexes. The method has the advantages of easy realization and low calculating complexity, and is applicable to high-spectral remote sensing image waveband selection. The waveband selection result is applicable to high spectral remot
