Abstract:
Methods, systems and devices for using flexible and efficient partitioning techniques and in particular, restricting extended quadtree (EQT) partitioning, are described. An exemplary method for visual media decoding includes making a decision, based on one or more conditions, regarding a selective inclusion of one or more signaling bits for a partitioning process in a bitstream representation of a current visual media block of a plurality of visual media blocks, where the partitioning process splits the current visual media block into exactly four sub-blocks including at least one sub-block that has a size different from half of a width of the current visual media block times half of a height of the current visual media block; decoding, based on the bitstream representation, the four sub-blocks; and decoding, based on the four sub-blocks and the partitioning process, the current visual media block.
