Edge morphology attention mechanism and optimal geometric matching connection model for vascular segmentation

Yuntao Zhu, Yuxuan Qiao, Qun Zhou, Xiaoping Yang

Abstract: Highlights•A new two-stage approach fuses deep learning and geometric priors to repair vascular fractures and topology.•The first stage has a novel edge morphology attention mechanism to discriminate between fuzzy vessel boundaries.•The second stage uses an optimal geometric matching connection model to connect the broken vessels.
