Method and apparatus for generating chrominance shape information of a video object plane in a video signal |
摘要 |
<p>An apparatus generates chrominance shape information based on luminance shape information represented by binary values, to thereby describe an object in a video object plane effectively. The apparatus divides the luminance shape information into a multiplicity of sample blocks, a sample block including 2 x 2 pixels, and determines, for each sample block, a chrominance value based on all logic values in a sample block. The chrominance shape information is produced in a form of a matrix based on the chrominance values for all sample blocks. <IMAGE></p> |
