Survey on Change Detection in SAR Images with Image Fusion and Image Segmentation
Keywords:
Synthetic Aperture Radar (SAR), difference image, image fusion, image change Detection algorithms.Abstract
In this paper the pilot survey of the different image processing techniques and different core decision rules to detect change in Synthetic Aperture Radar images is carried out. Change detection in SAR images is much more difficult than that of optical images due to the existence of speckle noise and the complex mixture of terrain environment. Change Detection is identifying the differences between images of same area acquired during different instances. Its wide applications are positioning and hazard assessment of earthquake area, monitoring of crop growth conditions, detecting of urban land use. Typically change detection in SAR images is divided in two different modules first is Generating difference image and second one is Detection of change in difference image, hence in this paper we are discussing various methods to generate difference image, Image fusion techniques along with the change detection algorithm.
