用动态引导和全局局部校准,一次修复多种图像退化。
QuReC: All-in-One Image Restoration with Query-Specific Guidance and Local-Global Response Calibration

- 为每个空间位置生成退化感知的个性化引导信号。
- 在多个基准上达到领先性能,显著提升复杂退化场景下的修复效果。
- 适合需要统一处理多种退化的实际图像修复任务。
全功能图像修复旨在使用单一统一模型恢复由多种退化类型引起的图像。现有方法通常依赖图像级提示或共享引导来处理多样化退化,但在退化具有空间异质性或混合共存于单张图像时表现不足。仅靠空间自适应引导仍不够,因准确修复还需每个空间查询可靠聚合局部邻域与全局上下文的互补信息。为此,我们提出QuReC,一个统一的全功能图像修复框架,包含退化引导查询重建模块(DQRM)和局部-全局响应校准模块(LGRCM)。DQRM将每个空间查询与退化原型空间匹配,重建特定查询的退化感知表示,提供细粒度的空间自适应修复引导;为稳定查询匹配过程,引入弱监督原型匹配学习策略,提升优化稳定性和退化语义一致性。LGRCM通过双分支进行局部-全局聚合,并利用可学习先验校准聚合响应,增强特征聚合可靠性,协调局部细节建模与全局上下文建模。大量实验表明,QuReC在多个全功能图像修复基准上表现卓越。代码已开源:https://github.com/zhoushen1/QuReC。
原文摘要 · Abstract (English)
All-in-one image restoration aims to recover clean images degraded by multiple corruption types using a single unified model. Existing methods typically rely on image-level prompts or shared guidance to handle diverse degradations. However, such a paradigm becomes inadequate when degradations are spatially heterogeneous or even coexist in mixed forms within a single image. Yet spatially adaptive guidance alone is not sufficient, since accurate restoration also requires each spatial query to reliably aggregate complementary information from local neighborhoods and global contexts. To this end, we propose QuReC, a unified framework for all-in-one image restoration. QuReC consists of a Degradation-Guided Query Reconstruction Module (DQRM) and a Local-Global Response Calibration Module (LGRCM). Specifically, DQRM matches each spatial query against a degradation prototype space to reconstruct a query-specific degradation-aware representation, thereby providing fine-grained spatially adaptive restoration guidance. To further stabilize this query-wise matching process, we introduce a weakly supervised prototype matching learning strategy to improve optimization stability and degradation semantic consistency. Meanwhile, LGRCM performs local-global dual-branch aggregation and calibrates the aggregated responses with learnable priors, improving the reliability of feature aggregation and the coordination between local detail modeling and global context modeling. Extensive experiments demonstrate that QuReC achieves superior performance on multiple all-in-one image restoration benchmarks. The code is released at https://github.com/zhoushen1/QuReC.
