| Abstract: | Variable-sized block inter prediction mode decision of H.264/AVC was studied in this paper. The full search decision method and rate distortion optimization strategy of JM8.4 code were analyzed firstly. Then improved methods that had been proposed were classified, and the theories of some representative methods were introduced primarily. The ideas of different improved methods were concluded, and their advantages and disadvantages were compared with each other. Based on the work above, an optimal decision strategy was proposed finally. |
