MULTIRESOLUTION ELASTIC IMAGE REGISTRATION

We have developed a multiscale algorithm for elastic (or molded) align ment of images. There is a wide array of medical applications of elast ic (as opposed to strictly rigid) alignment: Subtraction of previous i mages from current ones to identify changes is perhaps the most obviou s. We present preliminary results of this molding technique on a varie ty of images, and conclude with some closing remarks about this and fu ture directions and goals of this work.
