Abstract An automatic optic nerve head localization method in the fundus images based on cross-network is studied in this paper. To describe the space properties of the retinal vessel, a new conception – cross-network and measures of the network are proposed. Based on the model of fundus organs structure, automatic localization of optic nerve head is realized using the cross-network’s measure parameter – cross density. Experimental results verify the effectiveness of the algorithm using the STARE, DRIVE fundus image databases and the clinic images over different image qualities. And it can satisfy the requirement of clinic ophthalmological diagnosis.
