Abstract

A region-based multi-criterion segmentation algorithm for image sequence coding is described in this paper. It is based on morphological segmentation, motion estimation, and compensation techniques. The concept of multi-criterion is introduced in the traditional gray-level segmentation process, which takes into account the high temporal redundancy. The current image is segmented into two different kinds of regions: homogeneous gray-level regions coded by texture modeling method or homogeneous motion regions represented by motion compensation. No prediction error needs to be transmitted. Contours are simplified by a new non-linear filter. Preliminary experimental results have demonstrated high potential performance, with the combination of the power of contour-texture approach and that of the motion compensation technique, for very low bitrate image sequence coding.
