Low-Complexity Encoding Method for H.264/AVC Based on Visual Perception

H.264/AVC standard 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 H.264/AVC, aiming at computing redundancy, based on the integration of visual selective attention mechanism and low complexity encoding of information analysis and visual perception, making use of the distribution of motion vector and the relationship between the mode decision probability and the human visual attention a low-complexity H.264/AVC video coding scheme is implemented in this paper. The simulation results show that the approach encoding effectively resolves the conflict between coding accuracy and speed, saving about 80% coding time on average, which effectively maintains good video quality and overall improves the encoding performance of H.264/AVC.
