Abstract
An apparatus comprises: a memory; and a processor coupled to the memory and configured to: obtain candidate MVs corresponding to neighboring blocks that neighbor a current block in a video frame, generate a candidate list of the candidate MVs, select final MVs from the candidate list, and apply constraints to the final MVs or a transformation to obtain constrained MVs.
