摘要:
研究了CIF分辨率的视频序列分别经过AVS-P2与H.264-baseline profile编码后,各种视频编码损伤的感知程度.通过3组主观实验得出了结论:就主观感知的模糊程度、色彩失真程度和块效应程度而言,H.264与AVS在CIF视频上没有显著性差异.并且进一步利用主成分分析和线性回归的方法,得出了各种编码损伤对主观图像质量影响的数学模型,模型具有良好的线性,同时给出结论:在低分辨率条件下,模糊程度和色彩失真程度对主观图像质量的影响相近,而块效应程度对主观图像质量的影响低于模糊程度和色彩失真程度对主观图像质量的影响.
Abstract:
Video of CIF(common intermediate format)resolution, coded by AVS(audio video coding standard)-Part2(AVS1-P2)and the H.264 baseline profile(H.264-BP)respectively, are used to study the perceptual strength of coding artifacts. The results of three subjective experiments indicate that there is no significant difference between the two encoders, as far as the perceptual strength of blurring,color-distortion and blocking is regarded. Meanwhile, by means of principal component analysis and linear regression method, the mathematical model with good linearity is developed, reflecting the coding artifacts’ influence on the image quality. It is concluded that the blurring strength and color-distortion strength have similar influence on the image quality of low resolution video, while the influence of blocking strength is relatively less.
