REGION-BASED VIDEO CODING USING MATHEMATICAL MORPHOLOGY

This paper presents a region-based coding algorithm for video sequence s. The coding approach involves a time-recursive segmentation relying on the pixels homogeneity, a region-based motion estimation, and motio n compensated contour and texture coding. This algorithm is mainly dev oted to very low bit rate video coding applications. One of the import ant features of the approach is that no assumption is made about the s equence content. Moreover, the algorithm structure leads to a scalable coding process giving various levels of quality and bit rates. The co ding as well as the segmentation are controlled to regulate the bit st ream. Finally, the interest of morphological tools in the context of r egion-based coding is extensively reviewed.
