We present a method for automatic surface comparison and alignment based on
principles from conformal geometry and optimal mass transportation.
One application of the method is efficient calculation of point
correspondences between surfaces. Another
application is a novel distance definition between disc-type surfaces which
forms a tractable alternative to the Gromov-Hausdorff distance.
Joint work with I. Daubechies and T. Funkhouser.
