VERFAHREN UND GERÄT ZUR KOMPAKTEN DARSTELLUNG DER KONTUR EINER DISKRETEN REGION

摘要

A method (900, 1000) and device (100, 600) are provided 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 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 for coding of shape information within object-based and region-based image and video compression systems.
