双路径编码和跨级解耦的视网膜血管分割
Dual-path encoding and cross-level decoupling for retinal vessel segmentation
摘要
Abstract
Retinal vessel segmentation is a critical foundation for ophthalmic disease diagnosis.However,existing methods have issues such as missed detection of thin vessels,interference from pathological re-gions,and feature entanglement.Therefore,this paper proposed a Dual-path Feature Extraction and Cross-level Feature Decoupling Network.First,in the encoder,a Multi-directional Differential Residual Block extracted vessel-edge features across multiple directions to capture subtle vessel structures.Next,a Collaborative Attention Fusion Block dynamically integrated the complementary convolutional features of the double-branch path,enhancing the aggregation of encoded information.Finally,for the skip connec-tions between the two U-Net branches,a Channel Interaction Disentanglement Block was introduced to decouple cross-level features,strengthen feature representations,and resolve the feature-confusion prob-lem inherent in traditional U-Net architectures.The proposed method was extensively validated on four public datasets—DRIVE,CHASEDB1,STARE,and IOSTAR—achieving F1-scores of 82.47％,80.71％,81.44％,and 82.01％,and sensitivities of 80.96％,80.23％,74.69％,and 76.92％,respectively.The F1 scores of the LadderNet algorithm are 81.66％,80.16％,80.92％and 79.69％,and the sensitivity is 77.06％,78.88％,73.64％and 71.24％,respectively.Compared to state-of-the-art methods,our approach shows good robustness and superior segmentation performance in the task of reti-nal vascular segmentation.关键词
