“…Since these images have hundreds of continuous observation bands across the entire electromagnetic spectrum, more spectral information can be obtained when they are used. Therefore, they are widely used in atmospheric detection [3], [4], environmental monitoring [5], [6], geological prospecting [7], [8], military reconnaissance [9], [10], and other fields. HSI classification [11]- [14] uses the rich information contained in HSI to assign unique category labels for each pixel, which is an important aspect of HSI applications.…”
