Abstract:
A method of implictly encoding shape information for a video object, the method comprising:receiving a video frame that includes a video object; creating a box bounding the video object, the bounding box divided into a plurality of macroblocks, each macroblock comprising a plurality of chrominance and luminance pixels; replacing a first set of pixels that are in a first macroblock with a key color, wherein the first macroblock is on the object boundary and the first set of pixels are outside the object boundary; coding a first set of macroblocks to obtain a first coded set of macroblocks and coding a second set of macroblocks to obtain a coded second set of macroblocks, wherein the first set of macroblocks is on the object boundary and includes the first macroblock, and wherein the second set of macroblocks is inside the object; and outputting a bitstream including the first coded set of macroblocks and second coded set of macroblocks.
