面向低延迟应用的基于H.264编码视频率失真控制的编码估计

Coding Estimation based on Rate Distortion Control of H.264 Encoded Videos for Low Latency Applications

Amitesh Kumar Singam

AI总结:

本文针对低时空分辨率视频,研究了H.264编码条件对感知质量的影响,通过120种测试场景分析发现,视频质量问题并非源于糟糕编码,而是由率失真控制追踪出的信道容量所致。

摘要:

在视频处理领域,各种时空分辨率下视频压缩的进展是我们研究所需的,用于量化视频质量在空间和时间域内的位置。由于用户体验社区提出的糟糕编码问题,我们有必要研究相关视频编码条件对感知质量的影响。但大多数研究关注的是由糟糕编码引起的、针对高时空分辨率的编码失真。本文研究了具有低空间和时间频谱信息的视频序列的共120种测试场景。最终我们得出结论,即使在主观评分达到一致性后,我们在精炼主观评分后也获得了相关数据的一致性,因此这不是糟糕编码,而是由率失真控制追踪出的信道容量所致。

英文摘要:

In the field of video processing, advancements in video compression at various temporal and spatial resolutions which are needed in our research to quantify estimation of video quality whereabouts within spatial and temporal domain itself. It was necessary in our research to study the impacts of related video coding conditions upon perceptual quality due to issue raised by User Experience community regarding poor coding. But most of research studies are concerned with coding distortions affected by mostly due to poor coding which address high spatio-temporal resolutions. This paper presents overall 120 test scenarios for video sequences having low spatial and temporal spectral information were studied. Finally we concluded that even after achieving consistency within subjective scores, we got relevant data consistency after refining subjective scores, so it is not poor coding its due channel capacity which was traced out by rate distortion control.
