摘要:
A method estimates rate and distortion characteristics of a video object. First and second object shape features are respectively extracted at a first and second resolution of the video object. First and second rate distortion characteristics of the video object are respectively determined from the extracted first and second object shape features according to first and second modeling parameters. The extracted object shape features can be discrete, such as states of binary shape patterns of the video object, or the object shape features can be continuous such as a set of statistical moments representing a probability density function of the video object.
