UGC-VIDEO: perceptual quality assessment of user-generated videos
This work addresses the challenge of assessing video quality for user-generated content, which is crucial for platforms and users, but it is incremental as it primarily provides a new benchmark dataset.
The authors tackled the problem of perceptual quality assessment for user-generated videos by creating a database of 50 source videos from TikTok with multiple compression distortions and conducting subjective evaluations, revealing that existing algorithms have room for improvement.
Recent years have witnessed an ever-expandingvolume of user-generated content (UGC) videos available on the Internet. Nevertheless, progress on perceptual quality assessmentof UGC videos still remains quite limited. There are many distinguished characteristics of UGC videos in the complete video production and delivery chain, and one important property closely relevant to video quality is that there does not exist the pristine source after they are uploaded to the hosting platform,such that they often undergo multiple compression stages before ultimately viewed. To facilitate the UGC video quality assessment,we created a UGC video perceptual quality assessment database. It contains 50 source videos collected from TikTok with diverse content, along with multiple distortion versions generated bythe compression with different quantization levels and coding standards. Subjective quality assessment was conducted to evaluate the video quality. Furthermore, we benchmark the database using existing quality assessment algorithms, and potential roomis observed to future improve the accuracy of UGC video quality measures.
