Abstract

Diabetic retinopathy is a complication of diabetes that attacks the eye organs. One of the early signs of the disease is the appearance of an exudate wound that occurs because there is lipid in the abnormal blood vessels which can cause blindness if it appears around the macula. Early detection of exudates is expected to reduce the risk of blindness to diabetic retinopathy patients. One of the problems in the detection process of exudates is that the size of the object is quite small compared to the overall image. In this research, we propose the segmentation of exudates with saliency method based on region obtained using intensity thresholding. There are three main stages in this research, namely optic disc removal, location detection of exudates, and exudates segmentation. Optical disc removal is done using midpoint circle algorithm. At the detection stage of the exudates location, the image will be subdivided into …
