More Information
Summary:The invention relates to the field of image processing, and discloses a wave band selection method, which is one of effective means for reducing data dimensions of a hyperspectral image and retaining spectral information at the same time, and is different from a dimension reduction method of dimension reduction through linear or nonlinear transformation. The real spectrum data information can be completely reserved through band selection, the band selection method based on sorting is selected and used, the band selection method based on the combination of JS divergence and mutual information is provided, the characteristic that the JS divergence and the mutual information have symmetry is utilized, and the spectrum data information can be obtained through the band selection method based on combination of the JS divergence and the mutual information. The finally obtained spectrum comprehensive information matrix is a symmetric matrix, only the upper triangle or lower triangle part needs to be calculated, the c
