Application of Textural Features to Change Detection in SAR Image

Urban change detection that can provide plenty of information about land use and urban development is one of the important applications of change detection techniques. Aiming at the special use on urban environment, a change detection method of image differencing based on textural features is presented according to the characteristics of Synthetic Aperture Radar(SAR) image in this paper. The texture differencing change detection method substitutes textural features for gray information to represent the characteristics of images and gets urban change status through differencing change detection.The experimental result shows that a higher change detect accuracy can be obtained through the texture differencing method than through the traditional image differencing method based on gray level for most features,and an obvious improvement on detect performance also can be obtained through this new method.
