Task-Utility IQA: Rethinking Image Quality Assessment in Embodied Tasks

Read the original on arXiv AI →

The paper proposes rethinking image quality assessment (IQA) for embodied tasks by moving from generic score regression to goal‑conditioned judgments based on task utility. It introduces an MLLM‑based IQA agent that reasons about task requirements, grounds quality evidence, and outputs decision‑facing assessments. Experiments on VisDrone show that conventional perceptual metrics and generic IQA scores poorly predict downstream VLM task success, whereas a task‑conditioned utility score better indicates whether visual input supports the target task.

VGIQA: Fine-Grained Image Quality Assessment with Visual Grounding Rewards

VGIQA is a new image quality assessment model that provides both local and global quality evaluations. It uses a two‑stage training process—starting with a cold‑start phase and then reinforcement learning guided by local quality reward functions. The model demonstrates superior performance on the newly introduced VGSR‑2K dataset, outperforming existing open‑source multi‑modal large language models such as Qwen2.5‑VL‑72B‑Instruct and Qwen3‑VL‑32B‑Instruct, and it also improves degradation perception tasks.

PreResQ-R1: Response-Preference Disentangled Ranking-and-Scoring Reinforcement Optimization for Robust Visual Quality Assessment

PreResQ‑R1 introduces a Preference‑Response Disentangled Reinforcement Learning framework for Visual Quality Assessment that jointly optimizes absolute score regression and relative ranking consistency. It employs a dual‑branch reward system—modeling intra‑sample response coherence and inter‑sample preference alignment—trained with Group Relative Policy Optimization. The method extends to video quality assessment via a global‑temporal and local‑spatial data flow strategy, achieving state‑of‑the‑art results on 10 IQA and 5 VQA benchmarks with only 6K images and 28K videos, and provides human‑aligned reasoning traces.

VGIQA: Fine-Grained Image Quality Assessment with Visual Grounding Rewards

VGIQA is a new image quality assessment model that provides both local and global quality evaluations. It uses a two-stage training process—initial cold-start followed by reinforcement learning—with local quality reward functions. The model outperforms existing large multimodal language models on the newly introduced VGSR-2K dataset and improves performance on degradation perception tasks.
