Title
A Layered Structure Prediction Method for Mode Decision in Video Encoding
Abstract
Layered structure anticipation method for inter-frame prediction based on the spatial-temporal correlation and mode homology features of encoding block is proposed in this paper. Firstly, the non-equilibrium distribution of inter prediction is found, and a temporal-spatial related fast mode decision algorithm is proposed to realize a pre-determination of intra or inter mode in the P frame encoding. According to the analysis of multi-block-size of inter prediction and temporal-spatial continuity and consistency, design and implement multi-layer fast inter mode decision algorithm including skip mode pre-decision, macro-block division mode prediction and sub-block segmentation mode chosen. Simulation results show that the proposed algorithm can achieve reduction of 70.01% encoding time on average compared by exhaustive search algorithm for H.264/AVC. It obtains a significant reduction in the computational complexity without degradation in quality, which achieves robustness and comprehensive optimization of encoding performance.
