New VQA method uses explicit regional representations and vision-language models

Researchers have developed a new method for video quality assessment (VQA) that explicitly represents regional evidence, moving beyond implicit pixel-level analysis. This approach, called Quality-Relevance Heatmap (QRH), integrates localized degradation information with perceptual priors guided by vision-language models, eliminating the need for pixel-level annotations. Experiments using QRH with fragment-sampling strategies on the DOVER benchmark demonstrated that this method can closely approximate existing VQA model predictions and even improve performance on various benchmarks, suggesting explicit regional representations are a valuable tool for VQA.
