Abstract
In a morphing system for creating intermediate images that, viewed serially, make an object in a source image appear to metamorphose into a different object in a target image, correspondences between feature points in the source and target images are determined by simulating the modes of motion of respective elastic sheets in which are embedded nodal points that correspond to respective feature points in the images. For each feature point, a generalized-feature vector is determined whose components represent the associated nodal point's participations in the various motion modes. Correspondences between feature points in the source and target images are determined in accordance with the closeness of the points' generalized feature vectors. Correspondences thus determined can additionally be used for alignment and object-recognition purposes.
