VQAThinker: Exploring Generalizable and Explainable Video Quality Assessment via Reinforcement Learning

AAAI 2026technical

Video quality assessment (VQA) aims to objectively quantify perceptual quality degradation in alignment with human visual perception. Despite recent advances, existing VQA models still suffer from two critical limitations: poor generalization to out-of-distribution (OOD) videos and limited explainab

Q-Align: Teaching LMMs for Visual Scoring via Discrete Text-Defined Levels

ICML 2024poster

The explosion of visual content available online underscores the requirement for an accurate machine assessor to robustly evaluate scores across diverse types of visual contents. While recent studies have demonstrated the exceptional potentials of large multi-modality models (LMMs) on a wide range o…

Blind Image Quality Assessment via Vision-Language Correspondence: A Multitask Learning Perspective

CVPR 2023poster

We aim at advancing blind image quality assessment (BIQA), which predicts the human perception of image quality without any reference information. We develop a general and automated multitask learning scheme for BIQA to exploit auxiliary knowledge from other tasks, in a way that the model parameter…

Perceptual Attacks of No-Reference Image Quality Models with Human-in-the-Loop

NeurIPS 2022accept

No-reference image quality assessment (NR-IQA) aims to quantify how humans perceive visual distortions of digital images without access to their undistorted references. NR-IQA models are extensively studied in computational vision, and are widely used for performance evaluation and perceptual optimi…
