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

Acceptability-Based QoE Models for Mobile Video
Wei Song,Dian Tjondronegoro +1 more
TL;DR: In this article, a set of acceptability-based QoE models, denoted as A-QoE, is proposed based on the results of comprehensive user studies on subjective quality acceptance assessments.

Review of objective video quality metrics and performance comparison using different databases
TL;DR: The results show that the resolution, the content of the sequence and the distortion type have a significant influence on the performances of VQA metrics, with a focus on the full reference metrics.

Metrics for Evaluating Video Streaming Quality in Lossy IEEE 802.11 Wireless Networks
TL;DR: This paper proposes a novel video quality evaluation methodology that not only considers the PSNR of a video, but also with modifications to handle the packet loss issue, and names it MPSNR, which rectifies the inaccuracies in traditional PSNR computation, and helps to approximate subjective video quality, Mean Opinion Score, more accurately.

3D Visual Discomfort Prediction: Vergence , Foveation, and the Physiological Optics of Accommodation
TL;DR: The 3D-AVM Predictor accounts for anomalous motor responses of both accommodation and vergence, yielding predictive power that is statistically superior to prior models that rely on a computed disparity distribution only.

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.
