Abstract:
An arbitrary shape coding method comprising the steps of:(a) determining whether or not a shape in a video object layer (VOL) is an arbitrary shape;(b) calculating the size of a video object plane (VOP) in each frame if the shape in the VOL is determined as being an arbitrary shape in the step (a);(c) coding information of each frame about whether or not all macroblocks in the VOP are opaque;(d) coding the VOP in macroblock units if the shape of each frame is determined not to be all opaque in the step (c); and(e) coding only motion and texture information in the VOP, by macroblock in two circumstances of (1) if the shape in the VOL is determined to be a non-arbitrary shape in the step (a) and if (2) the shape in the VOP in a frame is determined as all opaque in step (c).
