<p>The present invention provides a method (900, 1000) and device (100, 600) for encoding and/or decoding a compact representation of a discrete region contour for the purposes of image and video compression. The compact representation described in this invention provides bitstream scalability so that progressively larger subsets of the compact representation can be used to provide progressive better quality in the approximate reconstruction of the discrete region contours. The resulting device and method provide a means for coding of shape information within object-based and region-based image and video compression systems.</p> |
