| Abstract: | It is very important that using change detection technology based on high resolution satellite remote sensing images to update existing image and map database.In this paper,existing change detection algorithms are summarized,and a process of change detection based on high resolution satellite remote sensing images are proposed.The process includes four steps,pre-processing,classification,feature detection and change detection.And key algorithms in these steps are introduced in details.Then we carry on experiments on SPOT5 images with mathematics morphologic,and good results has been achieved. |
