Method and apparatus for block partition with non-uniform quad split
A method of video decoding includes acquiring a current picture and signaling information from a coded video bitstream. The method further includes determining, from the signaling information, whether the block is partitioned in accordance with a quad split partition type. The method further includes, in response to determining that the block is not partitioned in accordance with the quad split partition type, determining whether the block is partitioned in accordance with a split partition type. The method further includes in response to determining that the block is partitioned in accordance with the split partition type, determining whether the block is partitioned in accordance with a non-uniform quad split partition type in which the block is partitioned into four sub-blocks along a same direction. The method further includes in response to determining that the block is partitioned in accordance with the non-uniform quad split partition type, reconstructing the block.
