Abstract
A system and method for encoding a video image using object-based encoding. The system comprises a foreground encoding system for coding a foreground shape in a foreground object plane; and a background encoding system for coding a background object plane, wherein the background encoding system pads a masked area in the background object plane, and wherein the masked area is determined from data associated with the foreground shape.
Claims20
An object-based encoding system for encoding a video image, comprising:
- a foreground encoding system for coding a foreground shape in a foreground object plane;
- a padding system that pads a masked area in a background object plane, wherein the masked area is determined from data associated with the foreground shape;
- and
- a background encoding system for coding the background object plane.
A method of encoding a video image in an object-based encoding system, comprising:
- coding a foreground shape in a foreground object plane;
- padding a masked area in a background object plane, wherein the masked area is determined from data associated with the foreground shape;
- and
- coding the background object plane.
A program product stored on a recordable medium for encoding a video image in an object-based encoding system, comprising:
- means for coding a foreground shape in a foreground object plane;
- means for padding a masked area in a background object plane, wherein the masked area is determined from data associated with the foreground shape;
- and
- means for coding the background object plane.
