《Efficient Visual State Space Model for Image Deblurring》

一、模块介绍

论文速览：

卷积神经网络（CNNs）和视觉变换器（ViTs）在图像恢复方面表现出色。虽然ViTs通过有效捕捉长距离依赖关系和输入特定特征总体上优于CNNs，但它们在图像分辨率增加时计算复杂性呈平方增长。这一限制妨碍了它们在高分辨率图像恢复中的实际应用。在本文中，我们提出了一种简单而有效的视觉状态空间模型（EVSSM）用于图像去模糊，利用状态空间模型（SSMs）在视觉数据中的优势。与现有方法采用几种固定方向扫描进行特征提取显著增加计算成本相反，我们开发了一个高效的视觉扫描块，在每个基于SSM的模块之前应用各种几何变换，捕捉有用的非局部信息并保持高效率。此外，为了更有效地捕捉和表达局部信息，我们提出了一种基于高效判别频域的前馈网络（EDFFN），该网络可以有效估计有用的频率信息以恢复潜在清晰图像。大量实验结果表明，所提出的EVSSM在基准数据集和实际图像上相较于最新方法表现良好。

总结：本文更新其中的EDFFN模块。

2.2更改yaml文件 (以自研模型为例)

yam文件解读：YOLO系列 “.yaml“文件解读_yolo yaml文件-CSDN博客

打开更改ultralytics/cfg/models/11路径下的YOLOv11.yaml文件，替换原有模块。
