Detection of Optic Disc Center and Macula using Spatial Information of Optic Cup

摘要：

The Optic Disc is a circular and bright region in retinal fundus images. Macula is a yellow portion of the posterior retina, lateral to the optic nerve, with a depression in its center. This paper presents an approach to detect optic disc center and macula using spatial information of optic cup. Optic Cup is a region in optic disc with the brightest pixel values. The proposed method is based on morphological, adaptive thresholding and arithmetic operations. It is computationally efficient and fast. It performs well even when there are unhealthy and low quality retinal images.
