摘要
Abstract
The optic disc image segmentation is very important for fundus image analysis and computer‐aided diagnosis of retinal optic nerve disease .In this paper ,a novel method for optic disc localization is presented by applying gratitude vec‐tor field(GVF) snake model to a background image without vessels .Firstly ,the vessels are filtered from the original image and the partly background is obtained .And then a fitting method is used to recover the whole background image without ves‐sels .This background image gets rid of the influence of complex blood vessels and other barriers and makes the optic disc easier to be detected .Finally GVF snake model is applied to detect the optic disc from the background image with an initial Hough circle .Plenty of experiments on different medical fundus images show that the new‐presented algorithm has a better segment results than the methods using the GVF snake model directly .关键词
