Abstract
An improved video information coding method for an object boundary block merging/splitting technique which makes it possible to use an object boundary block merging and a merging/separation as a reverse process thereof which are capable of enhancing a coding efficiency by using a space surplus of an intra-video and inter-video which exist in a block or a neighboring block by merging, coding and transmitting the BBM. The method includes the steps of merging a plurality of object boundary objects, judging whether there is an overlapped block signal among the block signals using shape information of the object boundary blocks, and merging the blocks in which no overlapped pixels exist as a result of the judgement.
Claims12
A video information coding method in which texture information for a plurality of object boundary blocks is coded using a block merging/splitting technique, wherein each object boundary block includes a plurality of pixels by which it is possible to judge an object, each pixel having shape information and coordinated position information, the coding method comprising the steps of:
- selecting a first object boundary block and a second object boundary block from the plurality of object boundary blocks;
- rotating the pixels of the second object boundary block by 180°;
- merging the first object boundary block and the rotated second object boundary block by combining the pixels of the first object boundary block and the rotated pixels of the second object boundary block;
- comparing the shape information of the pixels of the first object boundary block and the shape information of the rotated pixels of the second object boundary block in a sequence of the coordinates of the pixels of the first object boundary block and judging whether a corresponding pixel is overlapped with respect to shape information between the first object boundary block and the rotated second object boundary block;
- and
- coding the texture information of the merging blocks in which the overlapped shape information does not exist as a result of the judgment.
