Block size restriction for illumination compensation

Abstract:

Systems, methods, and computer-readable storage media for restricting block sizes for illumination compensation are described. An example method can include obtaining a block of a picture of video data; determining a size of the block; determining whether the size of the block is equal to or less than a first block size associated with a block size restriction that restricts bi-directional inter-prediction for blocks having a respective size that is equal to or less than the first block size associated with the block size restriction or whether the size of the block is greater than a second block size associated with a video coding pipeline structure; and disabling illumination compensation for the block based on a determination that the size of the block is equal to or less than the first block size or greater than the second block size.
