Remote sensing image segmentation is the basis of image pattern recognition. It is significant for the application and analysis of remote sensing images. Clustering analysis as a non-supervised learning method is widely used in the segmentation of remote sensing images. It has made good results in the segmentation of low-resolution and moderate-resolution remote sensing images. As the improvement...
Integration of spectrum, texture and shape information, evidence theory is introduced to land covers classification of high-resolution images, and an object-oriented land covers classification method of high-resolution images based on Dempster-Shafer evidence theory is proposed. Firstly, for image objects, four kinds of indexes are selected as attributes to discriminate different land cover types,...
