一种新型基于利用全色锐化技术的插值高光谱图像亚像元定位
A novel interpolation-based subpixel mapping for hyperspectral image by using pansharpening
摘要
Abstract
In this paper,a novel interpolation-based subpixel mapping(ISPM)for hyperspectral image by usingpansharpening(PAN-ISPM)is proposed. In the proposed method,a novel processing path is added into the exist-ing processing path of ISPM. Firstly,the original coarse hyperspectral image is improved by pansharpening tech-nique in the novel processing path,and the novel fine fraction images are derived by unmixing the improved im-age. Secondly,the novel fine fraction images from the novel path and the existing fine fraction images from the existing path are integrated to produce the finer fraction images with more spatial-spectral information. Finally, according to the predicted values from the finer fraction images,class labels are allocated into subpixel to obtain the final mapping result. Experimental results show that the proposed method produces the higher mapping accura-cy than the existing ISPM methods.关键词
