2025年2月2日 · 在 CVPR 2021 上发表的 “Rich Features for Perceptual Quality Assessment of UGC Videos” 中，我们描述了如何尝试通过构建类似于主观质量评估的通用视频质量模型（UVQ）来解决 UGC 质量评估问题。 UVQ 模型使用子网络从高级的语义信息到低级的像素失真来分析 UGC 质量，并提供可靠的质量评分（利用全面且可解释的质量标签）。 此外，为了推进 UGC-VQA 和压缩研究，我们增强了开源的 YouTube-UGC 数据集，其中包含来自 YouTube 上 …

This repository contains checkpointed models of Google's Universal Video Quality (UVQ) model. UVQ is a no-reference perceptual video quality assessment model that is designed to work well on user-generated content, where there is no pristine reference.

2022年8月23日 · We present the open-source UVQ model, which generates a report with quality scores and insights that can be used to interpret UGC video perceptual quality. UVQ learns comprehensive quality related features from millions of UGC videos and provides a consistent view of quality interpretation for both no-reference and reference cases.

2022年8月30日 · In "Rich Features for Perceptual Quality Assessment of UGC Videos", published at CVPR 2021, we describe how we attempt to solve the UGC quality assessment problem by building a Universal Video Quality (UVQ) model that resembles a subjective quality assessment.

In “Rich Features for Perceptual Quality Assessment of UGC Videos“, published at CVPR 2021, we describe how we attempt to solve the UGC quality assessment problem by building a Universal Video Quality (UVQ) model that resembles a subjective quality assessment. The UVQ model uses subnetworks to analyze UGC quality from high-level semantic ...

For example, Wang et al. proposed a feature-rich NR VQA model named UVQ, which incorporates features extracted from three pre-trained models, including compression level classification, action recognition, and distortion type classification.

Update — 2022/11/08: This post has been updated to include open-source details for the UVQ model. Online video sharing platforms, like YouTube, need to understand perceptual video quality (i.e., a user's subjective perception of video quality) …
