Towards Open-ended Visual Quality Comparison
Comparative settings (e. g. pairwise choice, listwise ranking) have been adopted by a wide range of subjective studies for image quality assessment (IQA), as it inherently standardizes the evaluation criteria across different observers and offer more clear-cut responses.
A Benchmark for Multi-modal Foundation Models on Low-level Vision: from Single Images to Pairs
To this end, we design benchmark settings to emulate human language responses related to low-level vision: the low-level visual perception (A1) via visual question answering related to low-level attributes (e. g. clarity, lighting); and the low-level visual description (A2), on evaluating MLLMs for low-level text descriptions.

Recent advancements in Multi-modality Large Language Models (MLLMs) have demonstrated remarkable capabilities in complex high-level vision tasks.
Iterative Token Evaluation and Refinement for Real-World Super-Resolution
Distortion removal involves simple HQ token prediction with LQ images, while texture generation uses a discrete diffusion model to iteratively refine the distortion removal output with a token refinement network.
Exploring the Naturalness of AI-Generated Images
In this paper, we take the first step to benchmark and assess the visual naturalness of AI-generated images.
Enhancing Diffusion Models with Text-Encoder Reinforcement Learning
While fine-tuning the U-Net can partially improve performance, it remains suffering from the suboptimal text encoder.
Q-Instruct: Improving Low-level Visual Abilities for Multi-modality Foundation Models
Multi-modality foundation models, as represented by GPT-4V, have brought a new paradigm for low-level visual perception and understanding tasks, that can respond to a broad range of natural human instructions in a model.
Q-Bench: A Benchmark for General-Purpose Foundation Models on Low-level Vision
To address this gap, we present Q-Bench, a holistic benchmark crafted to systematically evaluate potential abilities of MLLMs on three realms: low-level visual perception, low-level visual description, and overall visual quality assessment.
Local Distortion Aware Efficient Transformer Adaptation for Image Quality Assessment
Further, we propose a local distortion extractor to obtain local distortion features from the pretrained CNN and a local distortion injector to inject the local distortion features into ViT.
TOPIQ: A Top-down Approach from Semantics to Distortions for Image Quality Assessment
Our approach to IQA involves the design of a heuristic coarse-to-fine network (CFANet) that leverages multi-scale features and progressively propagates multi-level semantic information to low-level representations in a top-down manner.

Generative models have recently exhibited exceptional capabilities in text-to-image generation, but still struggle to generate image sequences coherently.
Towards Explainable In-the-Wild Video Quality Assessment: A Database and a Language-Prompted Approach
Though subjective studies have collected overall quality scores for these videos, how the abstract quality scores relate with specific factors is still obscure, hindering VQA methods from more concrete quality evaluations (e. g. sharpness of a video).
Towards Robust Text-Prompted Semantic Criterion for In-the-Wild Video Quality Assessment
The proliferation of videos collected during in-the-wild natural settings has pushed the development of effective Video Quality Assessment (VQA) methodologies.
