Optic disk detection and segmentation approaches based on vessel network
Version 1Precise localization of the optic disk (OD) in retinal images is one of the challenges in ophthalmic image processing. Although many efforts have been made towards finding automated numerical solutions, they often fail on retinal images characterized by poor quality. Therefore, we introduce three novel methods namely, Vessel Transform (VT), Vessel Vector based Phase Portrait Analysis (VVPPA), and Hybrid Approach (HA) for automatic detection of the OD based primarily on retinal blood vessels.
