Uniformity is • Range of MOS over all test images/videos in the database, somewhat mixed, with few databases doing very well A set of No Reference metrics to evaluate the level of distortion (like blocking and blurring) present in a video file is offered by Department of Telecommunications, AGH University of Science and Technology. Indicators of the following artefacts can be found on their website. Video metrics: Blockiness. Blur. Exposure time distortion. Interlace VQA. Further, the VQEG database was designed to address the needs of secondary distribution of television and hence, the database spans narrow ranges of quality scores - indeed, more than half of the sequences are of very high quality (MPEG-2 encoded at > 3Mbps). Overall, the VQEG videos exhibi This paper describes a quality assessment model for perceptual video compression applications (PVM), which stimulates visual masking and distortion-artefact perception using an adaptive combination of noticeable distortions and blurring artefacts. The method shows significant improvement over existing quality metrics based on the VQEG database, and provides compatibility with in-loop rate.

The VQEG FR-TV Phase I Database on which we have stated performance results has been criticized in several regards. First, the database contains a limited set of distortion types (mostly arising from compression) that occur in television systems, and does not include distortions created by modern compression algorithms such as H.264 StreamSim Encode and stream raw video material, with optional packet loss.

StreamSim is a useful tool which is able to encode raw video material with different settings and stream the encoded.

RMSE calculation on table two from [1] is omitted due the brevity of the supporting data presented on this document It is found that the MOVIE index delivers VQA scores that correlate quite closely with human subjective judgment, using the Video Quality Expert Group (VQEG) FRTV Phase 1 database as a test bed. Indeed, the MOVIE index is found to be quite competitive with, and even outperform, algorithms developed and submitted to the VQEG FRTV Phase 1 study.

The Video Quality Experts Group (VQEG) was formed in October 1997 to address video quality issues. The group is composed of experts from various backgrounds and affiliations, including participants from several internationally recognized organizations working in the field of video quality assessment. The majority of participants are active in. The database is composed of 59520 sequences (10 different contents at three different resolutions each, encoded with 1984 different encoding parameters). For all 59520 HEVC sequences in the database, the following objective quality metrics are available: PSNR (as computed by the VQMT software) SSIM (as computed by the VQMT software

Most reference and distorted videos are interlaced - hence visual artifacts in the reference as well as distorted video sequences. De-interlacing is inappropriate in a VQA framework. The VQEG database consists only of compression Therefore, the selection of reference images is highly important for an IQA database. The Video Quality Expert Group (VQEG) has proposed several criteria in selecting test videos that are also instructive for selecting reference images . According to VQEG, the reference images should stress both image color and luminance VQEG eLetter • Volume 1, Issue 2 • December 2014 32 designed subjective methods can be evaluated and validated based on this database. VQEG GroTruQoE3D database The database is called VQEG GroTruQoE3D (Ground Truth Quality of The network was trained using degradation indicators extracted from the VQEG Phase I video database, which describe the level of distortion suffered by the original video under spatial and temporal scopes. The proposed method obtained an excellent correlation with the subjective scores over this same database

We present a novel multi-scale framework for video quality assessment that models motion in video sequences and is capable of capturing spatio-temporal artifacts in digital video. Performance evaluation of the proposed metric on the VQEG database shows that the system is competitive with and even performs better than existing methods. I The proposed quality metric was tested by using LIVE video database. The experimental results show that the new index performance compared with the other NR-VQA models that require training on LIVE video databases, CSIQ video database, and VQEG HDTV video database. The values are compared with human score index analysis of DMOS
