Claim 3:
4. A method of decoding comprising:
obtaining local illumination compensation information associated with video information based on illumination changes in the video information and based on a plurality of motion vectors included in motion compensation information associated with the video information, the motion compensation information obtained based on an affine motion model; and
decoding the video information based on the local illumination compensation information and the motion compensation information;
wherein the video information comprises a first block including a first row of sub-blocks and a first column of sub-blocks, and the plurality of motion vectors comprises a group of motion vectors associated with a first subset of sub-blocks included in the first row of sub-blocks and a second subset of sub-blocks included in the first column of sub-blocks; and
wherein obtaining the local illumination compensation information is based on a set of reconstructed samples obtained based on the group of motion vectors; and
wherein the affine motion model comprises determining a local illumination compensation flag based on at least one affine control point associated with a second block neighboring the first block.
