  • 分解修复能力为共性专家和残差专家,避免重复参数。
  • 比最强基线快11.83倍,内存减少85.3%,平均PSNR提升1.05dB。
  • 适合需要高效通用修复的遥感图像应用,尤其处理复合退化场景。

无人机和卫星获取的遥感图像常受恶劣天气、光照变化及成像伪影影响,这些退化可能同时存在,导致全局分布偏移和局部结构损坏。尽管一体化图像修复提供了统一解决方案,但现有方法仍存在退化线索弱或隐式、多专家设计中因重叠行为导致的参数冗余问题。本文提出CoRE-UIR(通用图像修复的共性与残差专家),基于共性-残差专家模块(CoRE),显式将修复能力分解为适用于所有退化的共性密集专家和针对特定退化的低秩残差专家,实现无冗余的自适应专精。在此基础上,退化先验嵌入(DPE)将冻结的CLIP特征转化为显式修复导向先验,全局特征调制(GFM)在局部残差补偿前对齐全局特征统计量。同时构建了大规模无人机修复数据集MDVD-108K(Multi-Degradation VisDrone),涵盖单退化与复合退化,并提供真实世界测试集。在多个数据集上的实验证明,CoRE-UIR在整体平均PSNR上提升1.05 dB,运行速度提升11.83倍,峰值内存降低85.3%(相较最强基线BaryIR),保持良好质量-效率权衡。下游任务和未见退化评估也验证了其泛化能力。代码与数据集将在https://github.com/zzaiyan/CoRE-UIR发布。

原文摘要 · Abstract (English)

Remote sensing images acquired by unmanned aerial vehicles (UAVs) and satellites are often degraded by adverse weather, illumination variation, and imaging artifacts, which may co-occur and jointly induce global distribution shifts and local structural corruption. Although All-in-One image restoration offers an appealing unified alternative to task-specific pipelines, existing methods still suffer from weak or implicit degradation cues and parameter redundancy caused by full-rank multi-expert designs with overlapping restoration behaviors. We propose CoRE-UIR (Common and Residual Experts for Universal Image Restoration), a prior-guided global-local framework centered on the Common-and-Residual Expert Block (CoRE). CoRE explicitly decomposes restoration capacity into a common dense expert for degradation-invariant restoration and low-rank residual experts for degradation-specific compensation, enabling adaptive specialization without redundant expert replication. Built on this design, Degradation Prior Embedding (DPE) adapts frozen CLIP features into an explicit restoration-oriented prior, while Global Feature Modulation (GFM) aligns global feature statistics before local residual compensation. We also construct MDVD-108K (Multi-Degradation VisDrone), a large-scale UAV restoration dataset covering both single and compound degradations, together with a real-world test set. Extensive experiments on multiple datasets show that CoRE-UIR improves the overall average PSNR by 1.05 dB while running 11.83$\times$ faster and reducing peak memory by 85.3% relative to the strongest baseline, BaryIR, thereby maintaining a favorable quality-efficiency trade-off. Evaluations on downstream tasks and unseen degradation also validate the generalizability of CoRE-UIR. The code and dataset will be released at https://github.com/zzaiyan/CoRE-UIR.
