Abstract

The invention discloses a hyperspectral band selection method based on multi-data-set collaborative analysis, and a storage medium. The method comprises the following steps: acquiring K hyperspectral data sets; calculating fitness values of individuals in each initial population; performing crossover or mutation operation on parent individuals in a current population to obtain first offspring individuals; performing crossover operation on parent individuals among the current population according to a cross-data migration probability to obtain second filial generation individuals; updating the current population according to the fitness values and updating the cross-dataset migration probability according to a migration probability function; selecting individuals with a highest fitness value as an optimal wave band of the current population and outputting the optimal wave band. According to the invention, a hyperspectral multi-data-set waveband selection collaborative analysis framework is constructed, and the waveband selection performance of each data set is improved by using a same spectral range and similar spectrum-space structures of the data sets.

Description

technical field [0001] The invention belongs to the technical field of image processing, and in particular relates to a hyperspectral band selection method based on collaborative analysis of multiple data sets and a storage medium. Background technique [0002] Hyperspectral images are widely used in farmland detection, urban planning, atmospheric science, and military reconnaissance. Compared with other remote sensing images, hyperspectral can realize the simultaneous acquisition of ground object spatial information, radiation information and spectral information, so it has been widely studied. However, the high-dimensional data of hyperspectral images also brings challenges while providing rich spectral information. First, there is a correlation between adjacent spectral bands in hyperspectral images, and the information redundancy increases. Second, the detailing of spectral information leads to the "Hughes phenomenon" in classification. Finally, high-dimensional data h...
