Paper Abstract

This paper is concerned with image sequence coding based on motion estimation-compensation using a pel-recursive technique. Motion estimation achieved by minimization of a functional is improved by the incorporation of a discontinuity constraint on the optical flow. The prediction errors are vector quantized using lattices. Recent work enabled us to use truncated lattices (D4, E8, L16, ...) in pyramidal form to construct the codebooks. The coding results were achieved on real sequence image.
