It solves the point correspondence problem of selecting points on shapes defined as curves so that the points correspond across a data set. An efficient numerical implementation is presented and made available as open source Matlab code. The problems with the early {MDL} approaches are discussed. Finally the {MDL} approach is extended to an {MDL} Appearance Model, which is proposed as a means to perform unsupervised image segmentation." }
