现有基于深度学习的视网膜血管分割方法因仅依赖逐像素掩码监督,难以有效建模血管网络的全局连通性和复杂分支结构,常导致分割结果中出现血管断裂等结构性误差。为此,本文提出了一种基于U-Net的图结构化辅助监督视网膜血管分割网络。通过血管骨架引导的结构编码算法,将关键分叉点与连通关系转换为结构化监督信号,引导网络学习视网膜血管的拓扑结构特征。设计了多层次信息流注意力融合模块,有效融合视觉语义特征和拓扑结构特征,提升网络的结构表达能力。利用辅助监督机制,引导网络同时学习拓扑结构特征和视觉语义特征,以兼顾分割精度与血管形态一致性。在CHASEDB1、DRIVE和STARE数据集上的实验结果表明,本文网络在精准分割视网膜血管的同时,可有效减少血管断裂问题,为保障分割结果的生物学一致性提供了参考。
- Abstract:

Existing deep learning-based retinal vessel segmentation methods, relying exclusively on pixel-wise mask supervision, encounter significant challenges in effectively modeling intricate branching patterns and overall global connectivity features, which leads to structural anomalies such as vascular discontinuities in the segmentation results. Thus, a U-Net-based graph-structured auxiliary supervision network for retinal vessel segmentation is presented in this paper. Firstly, using a vessel skeleton-guided structural encoding algorithm, key bifurcation points and connectivity relationships are transformed into structural supervision cues, enabling the network to capture the global structural attributes of retinal vessels. Secondly, to achieve effective integration of visual-semantic and topological structural features, a multi-level information flow attention fusion module is designed, enhancing the network’s structural representation capability. Finally, an auxiliary supervision mechanism is utilized to guide the network in jointly learning topological structural features and visual-semantic features, balancing segmentation accuracy with vessel morphological consistency. Evaluation on CHASEDB1, DRIVE and STARE datasets reveals that the proposed network achieves accurate retinal vessel segmentation, while effectively mitigates vascular discontinuities issues, thereby providing a reference for preserving biological consistency of segmentation outcomes.
