Subpixel mapping of a spatial attraction model based on multishift spectral remote sensing images
摘要
Abstract
Because the current subpixel mapping methods based on multishift spectral remote sensing images rarely consider the effect of a point spread function,we propose a new subpixel mapping of a spatial attraction model based on multishift spectral remote sensing images.To generate coarse fractional images,multishift spectral remote sensing images are first unmixed;under the premise of considering the effect of a point spread function,area-to-point kriging interpolation is applied to the coarse fractional images,followed by filtering through ideal square wave filtering,and finally,the improved coarse fractional images are obtained using the spatial attraction model to up-sample the improved coarse fractional images,obtaining the upsampled fractional images and performing integration processing on the upsampled fractional images to generate the fine fractional images.After completing the above-mentioned image processing steps,the class labels are finally distributed to each subpixel by applying the class allo-cation method to obtain accurate mapping results.The experimental results on two sets of experimental datasets show that the proposed method achieves better localization than existing subpixel localization methods.关键词
