Automatic Detection of Exudates Using Morphological Approach

Abstract

Diabetic retinopathy (DR) is a sight threatening complication due to diabetes mellitus that affects the retina .The blindness due to DR can be prevented if detected early enough for treatment.Hence screening for early stage of DR is very important. An ophthalmologist uses an ophthalmoscope to visualize the blood vessels and his or her brain to detect the DR stages. The above pathology-based method is time consuming and often requires fluorescein angiograms for accurate diagnosis. It requires highly trained and skilled clinicians to perform the DR severity grading method. In this paper we have proposed a low cost retinal diagnosis system which can aid an ophthalmologist to quickly diagnose various stages of diabetic retinopathies.
