JDATT: A Joint Distillation Framework for Atmospheric Turbulence Mitigation and Target Detection
- 联合蒸馏框架统一处理湍流去噪和目标检测
- 模型体积减小50%以上,推理速度提升3倍
- 适合无人机、监控等资源受限场景
大气湍流会导致图像出现波纹、模糊和亮度波动,严重影响图像质量及下游视觉任务如目标检测。尽管基于Transformer和Mamba的深度学习方法在湍流抑制上取得进展,但其高复杂度和计算开销使其难以用于实时应用,尤其在远程监控等资源受限场景中。此外,将湍流抑制与目标检测分离处理导致效率低下且性能不佳。为此,我们提出JDATT:一种联合蒸馏框架,整合先进的湍流抑制与检测模块,并引入统一的知识蒸馏策略,在压缩模型的同时最小化性能损失。采用混合蒸馏方案:通过通道级蒸馏(CWD)和掩码生成蒸馏(MGD)实现特征级蒸馏,以Kullback-Leibler散度实现输出级蒸馏。在合成与真实湍流数据集上的实验表明,JDATT在视觉恢复和检测精度方面均优于现有方法,同时显著降低模型尺寸与推理时间,适用于实时部署。
原文摘要 · Abstract (English)
Atmospheric turbulence (AT) introduces severe degradations, such as rippling, blur, and intensity fluctuations, that hinder both image quality and downstream vision tasks like target detection. While recent deep learning-based approaches have advanced AT mitigation using transformer and Mamba architectures, their high complexity and computational cost make them unsuitable for real-time applications, especially in resource-constrained settings such as remote surveillance. Moreover, the common practice of separating turbulence mitigation and object detection leads to inefficiencies and suboptimal performance. To address these challenges, we propose JDATT, a Joint Distillation framework for Atmospheric Turbulence mitigation and Target detection. JDATT integrates state-of-the-art AT mitigation and detection modules and introduces a unified knowledge distillation strategy that compresses both components while minimizing performance loss. We employ a hybrid distillation scheme: feature-level distillation via Channel-Wise Distillation (CWD) and Masked Generative Distillation (MGD), and output-level distillation via Kullback-Leibler divergence. Experiments on synthetic and real-world turbulence datasets demonstrate that JDATT achieves superior visual restoration and detection accuracy while significantly reducing model size and inference time, making it well-suited for real-time deployment.
