AN OBJECTIVE VIDEO QUALITY METRIC BASED ON SPATIOTEMPORAL DISTORTION
"... This paper proposes an objective video quality metric based on an analysis of spatial and temporal distortions. Spatial quality features extracted from the spatiotemporal region of reference and distorted videos are used to express the spatial distortion. Temporal distortion, caused by frame freezin ..."

Towards video quality metrics for HDTV
- in Proceedings of the Second International Workshop on Video Processing and Quality Metrics, VPQM’06
, 2006
"... High Definition Television (HDTV) is the new generation broadcasting system, proposing a deeper immersion in action and better visualization comfort. New material is used (flat television screens, fast connection, high media storage, etc.) allowing better user experience than standard definition tel ..."

television (SDTV). Higher hardware prices will only be accepted if noticeable higher quality is reached. However, new features bring specific distortions but also enhancements for global quality. New techniques of quality assessment need to be developed in order to characterize the impact of each element
Design and Performance of a Digital Video Quality Metric
, 1999
"... The growth of digital video has given rise to a need for computational methods for evaluating the visual quality of digital video. We have developed a new digital video quality metric, which we call DVQ (Digital Video Quality) 1 .Here we provide a brief description of the metric, and give a prelim ..."

Objective Video Quality Metrics: A Performance Analysis
- in the 14th European Signal Processing Conference
, 2006
"... In the last years, the development of novel video coding technologies has spurred the interest in developing digital video communications. The definition of evaluation mechanisms to assess the quality of video will play a major role in the overall design of video communication systems. It is well-kn ..."

-known that simple energy based metrics such as the Peak Signal Noise Ratio (PSNR) are not suitable to describe the subjective degradation perceived by a viewer. Recently, new video quality metrics have been proposed in the literature that emulates human perception of video quality since it produces results which
Video Quality Metric for Temporal Fluctuation Measurement
"... Temporal fluctuation artifact is often observed in digitally compressed video. However, the fluctuation intensity cannot be correctly measured by the traditional image/video quality metric, e.g., the peak signal-to-noise ratio (PSNR), which only addresses on the quality of a single image. Although t ..."

Perceptual adaptation of Objective video quality metrics
- In Proc. Ninth International Workshop on Video Processing and Quality Metrics (VPQM
, 2015
"... The limitations of objective metrics such as PSNR in evaluating video quality are well known to experts but less know to general users. A video tool which exploits perceptual phenomena may report higher subjective quality but lower objective performance than a non-perceptual tool. This presents a pr ..."
