Comparative Analysis of Vessel Segmentation Techniques in Retinal Images

Azhar Imran, Jianqiang Li, Yan Pei, Ji-Jiang Yang, Qing Wang
2019 IEEE Access  
Moreover, we compared these approaches to the dataset, evaluation metrics, pre-processing and post-processing steps, feature extraction, segmentation methods, and induced results.  ...  Miscellaneous methods: These methods are mostly evaluated from 2004 to 2017 on STARE and DRIVE dataset with average accuracy and AUC is about 0.94 and 0.96 respectively.  ...  This is further intended to find the local information and a vessel profile model path in which not only vessel centerline but the width of every vessel is extracted correctly.  ...
