Shape Registration by Optimally Coding Shapes
IEEE Transactions on Information Technology in Biomedicine, 2008This paper formulates shape registration as an optimal coding problem. It employs a set of landmarks to establish the correspondence between shapes, and assumes that the best correspondence can be achieved when the polygons formed by the landmarks optimally code all the shape contours, i.e., obtain their minimum description length (MDL).
