| Abstract(in English) | In many fields the problem arises of how to obtain information about shape, or how to change the shape of objects in an image. To do this, we need a method for automatic extraction of shape information, and a representation which allows us easily to change the shape. One representation which is very convenient from this point of view uses a common prototype and describes the shape of any given object in terms of its deviation from this prototype. However, such a respresentation requires the establishment of correspondences (ie. a warping fucntion) between the given image and the prototype. In this paper we describe a method for the extraction of warping functions. The proposed method is based on a variational principle, and the warping function is obtained as a solution which minimizes a squared sum of pixelwise differences under smoothness constraints. In the rest of the paper we describe details of the method and its possible applications. |
