Purpose of the Study:
- To develop an advanced deep learning model for accurate retinal blood vessel segmentation.
- To address limitations of existing methods in handling complex retinal images.
Main Methods:
- A dual-path U-Net architecture with separate texture and structural branches.
- Integration of a cascaded dilated convolution module (CDCM) for multi-scale feature extraction.
- A boosting algorithm with probability distribution attention (PDA) to enhance shallow information and reduce overfitting.
Main Results:
- The proposed method achieved improved segmentation accuracy on CHASEDB1, DRIVE, and STARE datasets.
- Demonstrated superior performance compared to existing retinal blood vessel segmentation techniques.
- Effective handling of complex backgrounds and lesion areas.
Conclusions:
- The novel attention-based U-Net with CDCM and PDA significantly enhances retinal blood vessel segmentation.
