摘要
针对压缩传输对立体视频降质损伤的影响,进行大量主观实验获取评价数据,设计了一套合理的数据处理方法,并对处理后的实验结果进行了分析探究。该处理方法主要包括淘汰异常者、剔除异常值和均值化处理3 个步骤。实验结果表明,所述方法处理数据的能力明显优于传统的格鲁布斯检验法。利用上述实验数据处理方法,分析经H.264 压缩算法处理的立体视频实验数据,得出结论:量化参数(QP)的大小影响立体视频质量损伤度大小;参考视点携带的信息更占据主导地位;高分辨率视频有助于降质补偿;女性接纳视觉损伤的能力高于男性。探究所得结论为立体视频通信技术的优化提供技术支持。
Abstract
Aiming at the influence of compression and transmission on the degradation damage of stereo videos, a reasonable data processing method is designed based on the evaluation data obtained from lots of subjective evaluation experiments, and then the final processed results are analyzed. The method includes three aspects: weeding out abnormal cases, removing abnormal values and averaging values. The experimental results show that this method is obviously better than the traditional Grubbs test. The data of stereo videos processed by the H.264 compression algorithm are analyzed by the method above, and the conclusions are drawn: the quantization parameter (QP) affects the damage degree of video quality; information carried by the reference viewpoint takes a more dominant place; high- resolution videos contribute to the compensation of degradation; the ability of females to accept visual impairment is stronger than that of males. The conclusions provide technical support for the communication technology optimization of stereo videos.
