USE OF MOTION VECTORS IN EVALUATING GEOMETRIC PARTITIONING MODES |
摘要 |
During a video encoding process, rectangular prediction units (PUs) for a coding unit (CU) are generated. Furthermore, a geometric partitioning mode is used to generate a first and a second geometric PU for the CU. The first and second geometric PUs are associated with different geometric partitions of a sample block of the CU. One of the rectangular PUs is identified as overlapping the first geometric PU. The motion vector of the identified rectangular PU is used to identify a given area of a reference frame. The given area of a reference frame is then used as a starting point of a search to identify a reference sample for the first geometric PU. A motion vector for the first geometric PU indicates a position of the reference sample relative to a position of the first geometric PU. A prediction block is generated using the motion vector for first geometric PU.
