A new benchmark study evaluated five retinal vessel segmentation pipelines (FSG-Net, SA-UNetv2, DCP-1024, GAVE, and FR-UNet) across 244 images from six public datasets. The research found that no single pipeline performed optimally in all scenarios, with FSG-Net excelling in overall metrics like Macro-F1 and IoU, while SA-UNetv2 showed higher sensitivity, particularly for thin vessels. The study also highlighted that performance variations between datasets were often more significant than differences among the top-performing pipelines, and common errors occurred near vessel boundaries and faint peripheral vessels. Furthermore, the research demonstrated that local segmentation errors can be amplified in downstream vascular feature classification, suggesting the importance of task-conditioned pipeline selection and validation on the target domain.
