| Abstract: | H.264/AVC is the state-of-the-art video coding standard, which has various functions to realize high compression performance. The codec prepares several modes in both intra- and inter-prediction, and chooses the best one by some criterion. Therefore, the encoder requires a heavy burden. This paper describes a fast mode decision method on Sum of Absolute Transformed Differences (SATD) criterion. The proposed method prunes candidates by projecting difference blocks onto the canonical bases without calculating transformed differences, and guarantees to choose the best mode. Experimental results show that the proposed method reduces computational time by 16% compared with the exhaustive calculation performed by Joint Model (JM) 14.0. |
