The CVQA dataset focuses on the compressed video quality assessment problem. It contains 1,022 distorted streams, produced from 36 reference videos, which were originally collected using space-time-complexity clustering from a pool of more that 18,000 videos with the average bitrate of 130 Mbps. Coding artifacts were obtained by compressing videos through several encoders (32 in total) of different compression standards: H.265/HEVC, H.266/VVC, AV1, H.264/AVC, and VP9. There were two different presets (30 FPS and 1 FPS) and three target bitrates — 1,000 kbps, 2,000 kbps, and 4,000 kbps. More than 320,000 subjective scores were collected through the Subjectify.us crowdsourcing platform, which employs a Bradley-Terry model to transform the results of pairwise voting into a score for each video. Content includes nature, sport, humans close up, gameplays, music videos, water stream or steam, CGI, and user-generated content. Several effects and distortions are also presented: shaking, slow-motion, grain / noisy, too dark / bright regions, macro shooting, captions (text), and extraneous objects.

: SS methodCurrent video quality assessment methods mainly deal with videos with distortions generated in compression or capture process, few researchers focus on perceptual degradation caused by heavy haze in real outdoor scenes. However, assessment of haze level in such application scenario is important. For instance, in the advanced driver assistance system the accurate evaluation of haze level helps to properly release warning signals to drivers, which may avoid latent traffic accidents and save people’s lives. It is necessary to develop studies on haze video quality assessment for real outdoor scenes, and to build benchmark dataset for haze videos. To fill the gap of this benchmark lack, a real haze video database called RHVD was designed and constructed. The dataset contains 403 haze videos captured in real outdoor scenes, which were collected from the Flickr video sharing platform and post-edited in our lab. We conducted subjective quality assessment experiments on the RHVD dataset. Forty non-experts were recruited and asked to rate the haze levels for each of the video in the dataset. The original ratings were screened and normalized to calculate the final subjective scores. The RHVD dataset is free to download from the following website: https://drive.google.com/file/d/1zY0LwJ-yNB8u1JTAJU2X7ZkiYXsBX7BF/view?usp=sharing, or https://pan.baidu.com/s/11p78zwMXmUHMGDj8WDanPA with password RHVD.
