A Color Based Method to Identify Microaneurysms in Mild Stage of Non-Proliferative Diabetic Retinopathy

Keywords : Diabetic Retinopathy, Microaneurysms, Fundus Image


Abstract

Diabetic retinopathy (DR) is a diabetes related eye disease which occurs when blood vessels in the retina become swelled and leaks fluid which ultimately leads to vision loss. Several image processing techniques including Image Enhancement, Segmentation, Image Fusion, Morphology, Classification, and registration has been developed for the early detection of DR on the basis of features such as blood vessels, exudes, hemorrhages, and microaneurysms. The damage caused by diabetic retinopathy can be prevented by the early detection of microaneurysm in the retina. Microaneurysms are first medical sign of DR and they seem like red small dots in fundus image [1]. Presence of microaneurysms describes the levels of DR. Timely recognition of microaneurysms can reduce the risks of loss of sight. The proposed paper has discussed about the identification of microaneurysms using colors in digital image of fundus using different preprocessing and feature extraction technique.
