Abstract: In order to obtain a better classification method of remote sensing images and solve the problem of slow classification operation of hyperspectral remote sensing images, this paper integrates Lanczos algorithm and spectral clustering algorithm, discusses the feasibility of spectral clustering algorithm of hyperspectral remote sensing images applied to remote sensing image classification, and proposes a hyperspectral remote sensing image-oriented fast spectral clustering algorithm. By comparing the classification results of K-means algorithm and spectral clustering algorithm for hyperspectral remote sensing image of San Diego Airport, USA, it is found that spectral clustering algorithm for hyperspectral remote sensing image is easy to recognize linear features, and the classification speed can be greatly improved.
