Fast SAR Image Change Detection Using Bayesian Approach Based Difference Image and Modified Statistical Region Merging

Fast SAR Image Change Detection Using Bayesian Approach Based Difference Image and Modified Statistical Region Merging

A novel fast SAR image change detection method is presented in this paper. Based on a Bayesian approach, the prior information that speckles follow the Nakagami distribution is incorporated into the difference image (DI) generation process. The new DI performs much better than the familiar log ratio...
