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.
