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

Video quality assessment using motion-compensated temporal filtering and manifold feature similarity
TL;DR: The proposed VQA method using motion-compensated temporal filtering and manifold feature similarity appropriately processes temporal information in video by MCTF and temporal pooling strategy, and simulate human visual perception by MFL.

REQMM : Real-time end-user QoE monitoring middleware for IP-based commercial TV service
TL;DR: REQMM is a middleware which provides a novel video quality assessment method based on Decode Buffer probing, service failure detection and Request Response Time (RRT) calculation which has been integrated into over eight terminal models and will be put into large-scale commercial TV service of Shanghai Telecom.

Overview of full-reference video quality metrics and their performance evaluations for videoconferencing application
TL;DR: This work compares and evaluates the performance of 10 FR metrics with respect to their accuracy in predicting the subjective perceived quality for the videoconferencing application andphasis is given to the metrics evaluating the visual quality (from human perception).

Spatio-temporal quality pooling adaptive to distortion distribution and visual attention
TL;DR: The proposed scheme outperforms the traditional mean-based pooling scheme and shows competitive performance against well-known VQA algorithms when tested on two publicly available video quality databases.
Fast Low Bandwidth Model: A Reduced Reference Video Quality Metric
TL;DR: This memorandum describes the Fast Low Bandwidth model, which requires access to the original video at one location, the processed video at another location, and low bandwidth data link between the two locations, and is intended to help the reader understand the model from an algorithmic standpoint.

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.

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.

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.
