One of the visual indications for the presence of diabetic retinopathy is the exudates in the retina area of Fundus images. Detection of exudates is useful information for the early diagnosis of the eye disease. In this paper, a new approach for the detection of exudates is presented. A position based approach is combined with morphological operations for extracting the optical disc and detect the exudates. The proposed method is applied to the standard retinal image dataset and the results are presented.
