Method and apparatus for edge-based image encoding and decoding

摘要

The present invention provides for a method and apparatus for edge-based image and video encoding and decoding, especially for selective encryption application and flexible network services, which encodes separately edge-based information, by decomposing images into the following basic "natural" components: edge location; grey-tone/luminance and/or colour sampling along the edges (separately or as a whole with the previous one); residuum "smooth" image encoded according to any image description/compression standard. <IMAGE>
