针对无人机图像多重退化问题,提出解耦感知与重建的混合专家网络。

Compositional-Degradation UAV Image Restoration: Conditional Decoupled MoE Network and A Benchmark

  • 分因子显式感知退化,替代传统隐式纠缠条件。
  • 在43种组合退化下性能超越主流方法,尤其在未见场景提升显著。
  • 适合需要高精度图像修复的无人机巡检、遥感等应用。

无人机图像在大范围测绘、基础设施检测和应急响应中至关重要。然而,在真实飞行环境中,单张图像常受雨、雾、噪声等多种退化因素影响,降低下游任务性能。现有统一恢复方法依赖隐式退化表示,将多因素纠缠为单一条件,导致异质修正相互干扰。为此,本文提出DAME-Net:一种退化感知的混合专家网络,将显式退化感知与退化条件化重建解耦,实现组合式无人机图像恢复。具体地,设计了分因子退化感知模块(FDPM),通过多标签预测与标签相似性引导的软对齐,为恢复阶段提供显式的单因子退化线索,取代隐式纠缠条件,获得可解释且泛化性强的退化描述。同时,构建了条件解耦混合专家模块(CDMM),利用这些线索进行分阶段条件化、空频域混合处理及掩码约束的解耦专家路由,实现选择性因子特异性修复,抑制无关干扰。此外,构建了首个大规模组合式无人机图像恢复基准数据集MDUR,包含43种退化配置(从单退化到四因子复合),并提供标准化的已见/未见划分。在MDUR上的大量实验表明,相比代表性统一恢复方法,DAME-Net持续取得提升,尤其在未见及高阶复合退化上增益更大。下游目标检测实验进一步验证其在实际任务中的价值。

原文摘要 · Abstract (English)

UAV images are critical for applications such as large-area mapping, infrastructure inspection, and emergency response. However, in real-world flight environments, a single image is often affected by multiple degradation factors, including rain, haze, and noise, undermining downstream task performance. Current unified restoration approaches typically rely on implicit degradation representations that entangle multiple factors into a single condition, causing mutual interference among heterogeneous corrections. To this end, we propose DAME-Net, a Degradation-Aware Mixture-of-Experts Network that decouples explicit degradation perception from degradation-conditioned reconstruction for compositional UAV image restoration. Specifically, we design a Factor-wise Degradation Perception module(FDPM) to provide explicit per-factor degradation cues for the restoration stage through multi-label prediction with label-similarity-guided soft alignment, replacing implicit entangled conditions with interpretable and generalizable degradation descriptions. Moreover, we develop a Conditioned Decoupled MoE module(CDMM) that leverages these cues for stage-wise conditioning, spatial-frequency hybrid processing, and mask-constrained decoupled expert routing, enabling selective factor-specific correction while suppressing irrelevant interference. In addition, we construct the Multi-Degradation UAV Restoration benchmark (MDUR), the first large-scale UAV benchmark for compositional UAV image restoration, with 43 degradation configurations from single degradations to four-factor composites and standardized seen/unseen splits.Extensive experiments on MDUR demonstrate consistent improvements over representative unified restoration methods, with greater gains on unseen and higher-order composite degradations. Downstream experiments further validate benefits for UAV object detection.
