Region-based coding schemes are among the most promising compression techniques for
very low bit-rate applications. They consist of image segmentation, contour and texture
coding. This paper deals with the use of the geodesic skeleton as a morphological tool for
contour coding of segmented image sequences. In the geodesic case, already coded and
known regions are taken into account for the coding of contours of unknown regions. A new
technique is presented for the entropy coding of the coordinates of the skeleton points …
