A multi-frame pel-recursive algorithm for varying frame-to-frame displacement estimation

A pel-recursive two-dimensional motion estimation algorithm using three or more image frames is presented. It uses more information from the image sequences and gives a closed-form solution to update motion vectors among frame pairs simultaneously. Compared to other multiframe-based algorithms, the proposed algorithm is in a more general form. It is suitable for object motion with acceleration since it places no constraints on the displacement vectors among consecutive frames
