MFA-Net: 基于多视野上下文关注的视网膜血管分割

MFA-Net: retinal vessel segmentation based on multi-view context attention

  • 摘要: 视网膜血管图像分割在疾病的自动诊断中起着重要的作用,是早期诊断和手术规划的关键步骤.所以视网膜血管树的精确分割己成为计算机辅助诊断的先决条件.随着卷积神经网络在医学图像分割中的应用,一些分割性能优越的网络逐渐被提出.但是他们忽略了上下文多视野的关注,导致微血管分支很难分出.为了解决此问题,本文提出了一种多视野上下文关注的网络架构.该网络融入一个新的多视野关注模块,该模块能够在扩大感受野的同时关注有效信息,防止微血管分割断裂.其次网络融入注意力门控机制,将低级特征和高级特征相结合,产生更具代表性的新特征,进一步提升微血管分割的性能.在公开的两个眼底数据集DRIVE和CHASE DB1进行了评估,实验结果显示在准确率,灵敏度,交并比和AUC(ROC曲线下的面积)上均优于目前的新算法.

     

    Abstract: Retinal vascular image segmentation plays an important role in the automatic diagnosis of diseases, and is a key step in early diagnosis and surgical planning. Thus, accurate segmentation of the retinal vascular tree has become a prerequisite for computer-aided diagnosis. With the application of convolutional neural networks in medical image segmentation, some Network with optimized segmentation performance have been gradually proposed. However, these methods ignore the attention of context and multi-view, making it difficult to separate microvascular branches. To solve this problem, a multi-view context attention network architecture is proposed. Firstly, the network adds a new multi-view attention module, which can effectively focus on the valid information while expanding the receptive field, to prevent the fracture of microvascular segmentation. Secondly, the network integrates attention gate, it combines low-level features with high-level features, produced more representative new features, and further improve the performance of microvascular segmentation. It is evaluated on two public fundus datasets DRIVE and CHASE DB1, the experimental results show that the algorithm is superior to the state-of-the-art methods in accuracy, sensitivity, intersection-over-union and AUC (area under ROC curve).
