UGC-VIDEO: Perceptual Quality Assessment of User-Generated Videos [PDF]

2020 IEEE Conference on Multimedia Information Processing and Retrieval (MIPR), 2020
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

FOVQA: Blind Foveated Video Quality Assessment

IEEE Transactions on Image Processing, 2022
Previous blind or No Reference (NR) video quality assessment (VQA) models largely rely on features drawn from natural scene statistics (NSS), but under the assumption that the image statistics are stationary in the spatial domain. Several of these models are quite successful on standard pictures.

Comparing temporal behavior of fast objective video quality measures on a large-scale database [PDF]

, 2016
In many application scenarios, video quality assessment is required to be fast and reasonably accurate. The characterisation of objective algorithms by subjective assessment is well established but limited due to the small number of test samples ...

MRET: Multi-resolution transformer for video quality assessment

Frontiers in Signal Processing, 2023
No-reference video quality assessment (NR-VQA) for user generated content (UGC) is crucial for understanding and improving visual experience. Unlike video recognition tasks, VQA tasks are sensitive to changes in input resolution.
