Automatic Detection of Exudates in Retinal Images
Diabetic retinopathy is a major cause of blindness. Earliest signs of diabetic retinopathy are damage to blood vessels in the eye and then the formation of lesions in the retina. This paper presents an automated method for the detection of bright lesions (exudates) in retinal images. New methods are developed to localize and isolate the optic disk and detect the exudates. A novel algorithm presented to localize the optic disk and treat the confusion due to similarity between exudates and optic disk. The algorithm used specific color channels and some of image features to separate exudates from physiological features in digital fundus images. The algorithm is tested on many images from a published database and gives excellent and promise results.
Keywords: retina, optic disk, exudates, diabetic, retinopathy.
