esrj-90340	Pan, Hong; Khabazi, Mostafa	Study on the Evolution Monitoring of Topographic and Hydrological Characteristics of Small Watershed Based on Remote Sensing and GIS	2020	7	.pdf	application/pdf	6594	251	48	Group principal component images, use sparse representation method based on adaptive dictionary and dual-tree complex wavelet transform method to denoise principal component images with a small amount of information were the objectives of the paper; also the use the multi-scale wavelet transform to detect image edge; build a binary model of a pixel, extract vegetation index, and terrain factor based on a binary model of the pixel, and realize terrain and hydrological characteristics of the small watershed. On the basis of principal component analysis, the K-SVD model is used to denoise remote sensing images.	cache/esrj-90340.pdf	txt/esrj-90340.txt
