Abstract

Since image registering is still a difficult problem, the registered images of different time can not match on every pixel, which is usually caused by the differences of object projection from 3D to 2D. The projection differences are usually bigger for prominent objects such as buildings, especially on high resolution imagery, such as IKONOS, QuickBird. The misregistration of images will affect the results of change detection. A method is presented in this paper to lessen the effects of the misregistration. 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 an iterative radiometric calibration. At last, region change rate of segmented image are used to improve the change detection results. The experiments show that the false detection of misregistering can be reduced greatly.
