Abstract:
The present disclosure relates to deblocking filtering, which may be advantageously applied for block-wise encoding and decoding of images or video signals. In particular, the present disclosure relates to an improved memory management in an automated decision on whether to apply or skip deblocking filtering for a block and to selection of the deblocking filter. The decision is performed on the basis of a segmentation of blocks in such a manner that memory usage is optimized. Preferably, the selection of appropriate deblocking filters is improved so as to reduce computational expense.

Claim (Index 3):
A coding device decoding blocks of a frame, comprising:\n a processor; and a memory coupled to the processor; wherein the processor performs the following: dividing each of a first block and a second block that are separated by a first boundary into at least two segments along a line that is perpendicular to said first boundary, the first block and the second block being included in the frame; and judging whether or not to apply an in-loop deblocking filter to pixels adjacent to the first boundary of the first block and the second block, wherein the division of the first block and the second block into segments is performed such that a segment of one of the first block and the second block includes all pixels of said one of the first block and the second block required for: (i) judging whether or not to apply an in-loop deblocking filter; and (ii) selecting an in-loop deblocking filter for deblocking pixels adjacent to a second boundary, the second boundary being between a third block and said one of the first block and the second block, the third block is adjacent to said one of the first block and the second block, the third block is different from the first block and the second block, and the second boundary is perpendicular to the first boundary.
