基于3D相邻区域宏块相关性的多视点视频快速编码算法
Fast multi view video coding algorithm based on the relativity of 3 D adjacent areas macroblock
摘要
Abstract
Aimed at the high complexity of multi view video coding,a fast algorithm based on the correlation of adjacent macro-block’s coding information is proposed in this paper.Using the relativity of adjacent macro-block’s rate distortion cost distribution in inter views of multi view video,current macro-block’s SKIP mode can be prejudge.According to the motion vector difference in the adjoining domains from visual,temporal and spatial perspective,current macro-block’s mo-tion activity can be classified quickly.Search range is adjusted and suitable mode size is chosen in accordance with the dif-ferent motion activity.Through coding performance testing on multi view video sequences that has respective motion activity characteristics,the simulation results show that this algorithm achieves a reduction of the encoding time by 66% on aver-age,while incurring only 0.04 dB loss in peak signal-to-noise ratio and 0.75%increment on the total bit rate compare with JMVM ergodic model.关键词
