Abstract: In order to reduce the computational complexity of H.264 frame-skipping transcoding, an support vector machine (SVM) technology is employed in inter mode decision process, and a SKIP mode decision algorithm is proposed. Meanwhile, an early-termination strategy is used based on the temporal correlation between macro-blocks, and improbable candidate modes can be eliminated. In addition, an adaptive motion vector reconstruction and motion compensation algorithm is applied for sequences with different motions by measuring the motion activity of macroblocks, and the computational redundancy can be removed in case that the best matching motion vector can be found before motion search. Experimental results show that the coding time is reduced by an average of 84% dramatically while maintains the video image of high quality. Compared with the existing approaches, this algorithm is more robust and applicable.
