TLDR
The independent test results from the VQEG FR-TV Phase II tests are summarized, as well as results from eleven other subjective data sets that were used to develop the NTIA General Model.Abstract:
The National Telecommunications and Information Administration (NTIA) General Model for estimating video quality and its associated calibration techniques were independently evaluated by the Video Quality Experts Group (VQEG) in their Phase II Full Reference Television (FR-TV) test. The NTIA General Model was the only video quality estimator that was in the top performing group for both the 525-line and 625-line video tests. As a result, the American National Standards Institute (ANSI) adopted the NTIA General Model and its associated calibration techniques as a North American Standard in 2003. The International Telecommunication Union (ITU) has also included the NTIA General Model as a normative method in two Draft Recommendations. This paper presents a description of the NTIA General Model and its associated calibration techniques. The independent test results from the VQEG FR-TV Phase II tests are summarized, as well as results from eleven other subjective data sets that were used to develop the method.read more

An Innovative No-Reference Metric for Real-Time 3D Stereoscopic Video Quality Assessment
TL;DR: Results show that eNVQM maintains similar accuracy level in estimating 3D video quality with the alternative reference-based metrics, and is investigated by comparing its results with two state-of-the-art objective video quality metrics.

Exploiting just-noticeable difference of delays for improving quality of experience in video conferencing
Jingxi Xu,Benjamin W. Wah +1 more
TL;DR: This paper proposes a novel approach for improving the quality of experience (QoE) of real-time video conferencing systems by increasing MED to within JND in order to have more room for smoothing network delay spikes as well as recovering lost packets, without incurring noticeable degradation in interactivity.

Spatio-temporal quality pooling accounting for transient severe impairments and egomotion
TL;DR: The method accounts for localized severe impairments of the signal which exhibit significant influence on the subjective impression of the overall signal quality and accounts for the effect of camera motion on perceived quality.

DVQ: A digital video quality metric based on human vision
TL;DR: The Digital Video Quality (DVQ) metric as discussed by the authors is based on the Discrete Cosine Transform (DCT) and incorporates aspects of early visual processing, including light adaptation, luminance and chromatic channels, spatial and temporal filtering, spatial frequency channels, contrast masking, and probability summation.

Digital video quality metric based on human vision
TL;DR: A new digital video quality metric, which is based on the discrete cosine transform, which incorporates aspects of early visual pro- cessing, including light adaptation, luminance, and chromatic chan- nels; spatial and temporal filtering; spatial frequency channels; con- trast masking; and probability summation.
Video Quality Measurement Techniques
TL;DR: The goal of this report is to provide a complete description of the ITS video quality metric (VQM) algorithms and techniques, which provide close approximations to the overall quality impressions, or mean opinion scores, of digital video impairments that have been graded by panels of viewers.

PVQM – A perceptual video quality measure
Andries Pieter Hekstra,John G. Beerends,D. Ledermann,F. E. de Caluwe,S. Kohler,Robert Hendrik Koenen,S. Rihs,M. Ehrsam,D. Schlauss +8 more
TL;DR: A perceptual video quality system is proposed, that uses a linear combination of three indicators, the “edginess” of the luminance, the normalized color error and the temporal decorrelation, that showed the highest variance weighted regression overall correlation of all models.
