Method of generalized content-scalable shape representation and coding

摘要

A method for content-scalable shape representation is described. In content-scalable shape representation, the more important parts of the image are encoded using a larger number of bits within a single hierarchical layer, or within one or more layers of multiple hierarchical layers. This representation may be used with the framework of a hierarchical vertex-based shape representation technique. The method described herein provides for the representation of shapes either by selected verticles along a contour, or by binary bit maps. The resulting representation facilitates content-scalable coding.
