Abstract: Motion compensation using 2-D mesh models requires computation of the parameters of a spatial transformation within each mesh element (patch). It is well-known that the parameters of an affine (bilinear or perspective) mapping can be uniquely estimated from three (four) point correspondences (at the vertices of a triangular or quadrilateral mesh element). On the other hand, overdetermined solutions using more than the required minimum number of point correspondences provide increased robustness ... (Update)
