Automatic Optic Disc Center and Boundary Detection in Color Fundus Images
Accurately detection of retinal landmarks, like optic disc, is an important step in the computer aided diagnosis frameworks. This paper presents an efficient method for automatic detection of the optic disc’s center and estimating its boundary. The center and initial diameter of optic disc are estimated by employing an ANN classifier. The ANN classifier employs visual features of vessels and th...
متن کاملAutomatic Detection of Optic disc in Eye Fundus Images
In the automatic analysis of retinal images for diagnosing various eye diseases such as diabetic retinopathy, glaucoma etc. the automatic detection of the optic disc is a crucial step. Before processing the fundus image for detecting any type of retinal disease it is necessary to mask out the anatomical features of eye so that they will not be mistaken as abnormality. Optic disc often considere...
متن کاملMathematical Morphology based Optic Disc Detection in Retinal Fundus Images
Optic disc segmentation is a prerequisite in automatic analysis of retinal disease in color fundus images. In this paper, an algorithm for detection of optic disc (OD) in fundus images is presented. Mathematical morphology is used for segmentation of candidate optic disc region, followed by determining its center and approximating the circular optic disc boundary using circular model. Proposed ...

متن کاملFundus and Optic Disc Photography
l'rircuiar polarizers have been used v for difrerent ophthalmic applications, such as ophthalmoscopy,' lens photography,' and corneai endothelial microscopy.3 To the best of our knowledge, circular polarizers have not been applied to fundus photography. A linear polarizer polarizes light in a plane. In fundus photography, it has been used to show the birefringence of the nerve fiber layero and ...
