In this letter, a novel method is proposed for jointly unsupervised change detection and image
registration over multi-temporal optical remote sensing images. An iterative energy minimization scheme is
employed to extract the pixel opacity. Specifically, we extract the consistent points which provide the initial
seed nodes and the feature nodes for random walker image segmentation and image registration, respectively.
And the seed nodes will be updated according to the analysis of the changed and unchanged regions.
Experimental results demonstrate that the proposed method can perform change detection as well as the state
of the art methods. In particular, it can perform change detection rapidly and automatically over unregistered
optical remote sensing images.
Key words: Change detection, image registration, multi-temporal image, optical remote sensing image, random walker, ,
