A method is presented to decrease the effects of misalignment.Firstly,the images are registered with a reliable strategy so that the ground can be registered correctly.Then the changes of image are detected with traditional algorithm according to image difference based on iterative radiometric calibration.At last,change rate of segmented image regions are used to improve the change detection results.The experiments show that the false detection of misregistering can reduced greatly.
