This code refered to our proposed Adaptive Spatial-context Extraction Algoirhtm (ASEA) which is used to generate the change magnitude image (CMI) with very high spatial resolution. After obtaining CMI, double-window flexible pace search (DFPS) or Otsu can be adopted to achieve binary change detection map.

If you have any problems when running the code, please do not hesitate to contact us. Thanks.
