ABSTRACT
H.264/AVC encoder achieved excellent encoding performance of at the cost of increased computational complexity and falling encoding speed. In order to overcome poor real-time encoding performance of video encoding, aiming at computing redundancy, based on the integration of visual selective attention mechanism and low complexity encoding of information analysis, making use of the macro-blocks motion characteristics, a low-complexity motion estimation scheme is implemented in this study. The simulation results show that the approach encoding effectively resolves the conflict between coding accuracy and speed, achieve reduction of 23.11% motion estimation encoding time on average compared with UMHexagonS algorithm, which effectively maintains good video quality and overall improves the encoding performance of H.264/AVC video encoder.
