摘要

提出了一种针对多视点视频编码中Direct模式的提前终止算法.该算法基于当前编码宏块相邻视点、时间及空间方向的已编码邻近宏块的编码信息

提出了一个描述当前宏块的邻近块代价影响因子

通过与阈值比较可对多数编码宏块直接选择Direct模式进行编码

从而略过其他模式的相关计算.实验结果表明

与原始的多视点视频编码算法相比

该算法可平均减少约88.2%的编码时间

同时峰值信噪比仅下降约0.29 dB

编码比特率增加约0.68%.

Abstract

In order to reduce the encoders complexity

an early direct mode decision for MVC is proposed in this paper. Based on the best modes and their rate-distortion costs of encoded neighboring macroblocks which are located in the spatial

temporal and inter-view directions

the influence factor of neighboring macroblocks is used to describe the current macroblock. By comparing this influence factor with the threshold which is obtained by statistical analysis of error selection probability

the proposed algorithm directly select the direct mode for some macroblocks and ignore the calculation of the other remaining modes. The experimental results show that the proposed algorithm can achieve 88.2% of encoding time saving on average with little loss of coding performance with the reference full search encoder.
