移动多媒体广播无参考视频质量客观评价

摘要

重点研究了基于解压域的移动多媒体广播无参考视频质量客观评价方法,对不同测试序列在不同压缩码率下的受损图像进行了块效应和模糊度的算法分析,并利用线性加权的方法估计视频质量客观评价值.试验结果表明,采用的无参考客观评价值与全参考的PSNR值具有较强相关性,可用于终端用户的视频质量评价.%In this paper, the way for no-reference objective video quality assessment is emphatically researched based on decompressed domain of mobile multimedia broadcasting. The block effect and ambiguity algorithm of damaged image with different test sequences at different compression are analyzed, and the linear-weighted methods are used to estimate the value of objective evaluation of video quality. The experimental results show that the no-reference objective assessment value calculated by this algorithm has a strong correlation with PSNR, and it can be used for end users' video quality assessment.
