Study of Subjective and Objective Quality Assessment of Video
IEEE Transactions on Image Processing, 2010We present the results of a recent large-scale subjective study of video quality on a collection of videos distorted by a variety of application-relevant processes. Methods to assess the visual quality of digital videos as perceived by human observers are becoming increasingly important, due to the large number of applications that target humans as the

Subjective video quality prediction based on objective video quality metrics
2018 4th Iranian Conference on Signal Processing and Intelligent Systems (ICSPIS), 2018This A method is proposed for the generation of a set of video sequence with a predictive subjective video quality (Mean Opinion Score) based on a limited number of sequences and the associated objective video quality measure (Peak Signal-to-Noise Ratio). The MOS is predicted using a sigmoid function model that is optimized based on a limited number of

360-Degree Video Streaming and its Subjective Quality
SMPTE 2017 Annual Technical Conference and Exhibition, 2017Traditional challenges for end-to-end streaming services are harder when considering 360° video content. One of these challenges relates to the lack of standardized methodologies for subjective 360° video quality assessment, especially for streaming services. This paper presents a methodology for 360° video streaming services, which inherits a lot from

Subjective quality assessment of 3D videos
IEEE Africon '11, 2011Colour plus depth map based stereoscopic video has attracted significant attention in the last 10 years, as it can reduce storage and bandwidth requirements for the transmission of stereoscopic content over wireless channels such as mobile networks.

Large Scale Subjective Video Quality Study
2018 25th IEEE International Conference on Image Processing (ICIP), 2018Most of today's video quality assessment (VQA) databases contain very limited content and distortion diversities and fail to adequately represent real world video impairments. This is in part because conducting subjective studies in the lab is slow, inefficient and expensive process. Crowdsourcing quality scores is a more scalable solution.

CQA - Subjective Video Codec Quality Analyser
Procedings of the British Machine Vision Conference 1999, 1999A subjective video codec quality analyser (CQA) has been designed and implemented. It was specified to take two video streams as input: the original, uncompressed, stream and the compressed/decompressed stream. The CQA compared the subjective quality of the coded stream with respect to the uncoded one by computing the values of a number of factors ...

Automation of Subjective Video Quality Measurements
Proceedings of the Latin America Networking Conference on LANC 2014, 2014Quality of Experience is utterly important in Communication Systems, especially in audiovisual services. Audio and video quality, as perceived by the users, is one of the most important aspects that affect the Quality of Experience. The most accurate methods for measuring the perceived audio and video quality of a video clip are the subjective tests ...

HEVC subjective video quality test results
International Broadcasting Convention (IBC) 2014 Conference, 2014The primary goal for the development of the new High Efficiency Video Coding (HEVC) standard was to achieve a substantial improvement in compression efficiency relative to its predecessor, H.264/AVC. However, most comparisons to date had used simple objective measurements, rather than a formal subjective evaluation.
