- 摘要：
- <p><P>PROBLEM TO BE SOLVED: To prevent encoding efficiency from being reduced when indicating a shape or expansion rate of a region in start of decoding in a decoder concerning a method for indicating size, shape and location of a region within a digital picture, encoder, decoder and the like. <P>SOLUTION: The method for indicating size, shape and location of a region within a digital picture divided into a set of blocks is characterized in that a value for at least one size parameter which is indicative of a number of the blocks within the region of the digital picture is defined, and a value for at least one shape evolution parameter which is indicative of a selection order of the blocks in the region is selected. Then, preferably, the values for the at least one size parameter and the at least one shape evolution parameter are encoded into a bitstream of a video sequence in order to indicate size, shape and location of the region within the digital picture. <P>COPYRIGHT: (C)2006,JPO&NCIPI</p>
