Overview of SAR Image Change Detection Based on Segmentation

Change detection refers to the analysis of images at different moments, and then ascertaining the characteristics and processes of changes in the earth's surface. Change detection plays an important role in disaster dynamic monitoring, environment pollution monitoring and urban planning. In the technological society, change detection of SAR image becomes a significant research direction. This paper first describes the concept of SAR image change detection and introduces the traditional image change detection methods. Then are summarized various image change detection methods based on image segmentation. Finally, the existing problems and further development of image change detection are discussed.
