3 Subpixel Mapping Based on Single Remote Sensing Image
3.1 INTRODUCTION
The existing subpixel mapping based on a single remote sensing image is largely dependent on the high-resolution abundance images from subpixel sharpening. However, due to the low resolution of the original remote sensing image and the limitations of the existing spectral unmixing technology, the spatial-spectral information of the original remote sensing image is not fully utilized, which affects the final subpixel mapping results. In addition, when dealing with the subpixel mapping of a single remote sensing image, the spatial correlation information is not considered comprehensively and accurately, which will also reduce the accuracy ...
