In this paper, we propose a method for the automatic detection of exudates in digital fundus images. Our approach can be divided into three stages: candidate extraction, precise contour segmentation and the labeling of candidates as true or false exudates. For candidate detection, we borrow a grayscale morphology-based method to identify possible regions containing these bright lesions. Then, t...

Diabetic Retinopathy is a complication of diabetes that is caused by changes in the blood vessels of the retina. Diabetic retinopathy is a major cause of blindness. Earliest signs of diabetic retinopathy are damage to the blood vessels in the eye and then the formation of lesions in the retina. This paper presents an automated method for the detection of exudates in retinal images with high acc...

Out of the above classification DR is more prevalent in type 2 diabetes. DR is a results mainly due vascular changes in the retina. Exudates are one of the primary sign of Diabetic Retinopathy [1]. Retina is a light sensitive muscular layer which is nourished by a network of blood vessels. Any vascular change results in difficulties of light perception. Depending upon these vascular changes in ...

Diabetic retinopathy is recognised as one of the most common causes of blindness (Aiello et al., 1998). It can however be diagnosed early based on various features that can be detected in eye fundus images. One of these indicators is exudates which are typically formed in groups or rings surrounding leakage of plasma and often appear yellowish in the image. An example of a retinal image with ex...
