disthre = 1.5;        % the threshod of match errors the deflaut is 1.5. for
                      % high resolution image covering urban areas, we
                      % should set it to a larger threshod (such as 2.0).
                      % This is beccause that the geometric distortions between such images
                      % is very complicated, and the transfrom model used
                      % by us (such as projective model) can only prefit
                      % the geometric distortion. Therefore, a larger threshod
                      % have the more flexibility
