Detection of diabetic retinopathy by applying total variation.

The incendiary changes in the retina will lead to curative approaches that prevent blindness. Diabetic retinopathy is the most prevalent diabetic eye disease that produces intensive damage to the retina by creating progressive changes in its blood vessels. This can eventually lead to blindness. Diagnosis of this disease in its earlier phase is very important and this can be accomplished by a comprehensive eye examination and regular screenings. During the screening process, the images of the retina are taken by making use of an ophthalmoscope or a fundus camera. In this work, an attempt has been made to differentiate between an retinopathic eye from an healthy eye by applying total variation to the fundus photographs. Total variation measures the signal variation between successive signal values. Understanding
