摘要
在本文中，我们感兴趣的是为H.264/MPEG-4 (Motion Picture Expert Group) AVC (Advanced Video Coding)标准建立一个无参考的现有度量(MSU阻塞度量)的预处理。我们使用HARRIS显著性图进行预处理，以提高该指标的性能。我们通过使用主观的“LIVE”视频数据库来评估所提出的预处理的性能。性能指标，即Pearson (PLCC)和Spearman相关系数(SROCC)表明预处理在H264编解码失真中具有良好的性能。
A pretreatment using saliency map Harris to improve MSU blocking metric performance for encoding H264 / AVC : Saliency map for video quality assessment
In this paper we are interested in establishing a pretreatment for existing metrics without reference (MSU Blocking Metric) for the H.264/MPEG-4 (Motion Picture Expert Group) AVC (Advanced Video Coding) standard. We perform a pretreatment using HARRIS saliency map to improve the performance of this metric. We evaluate the performance of the proposed pretreatment by using subjective “LIVE” video databases. The performance metrics, i.e. Pearson (PLCC) and Spearman correlation coefficients (SROCC) indicate that the pretreatment gives a good performance in H264 codec distortions.
