Diabetic Retinopathy (DR) is the consequence of micro vascular retinal changes triggered by diabetes that can cause loss of vision if not treated in a timely manner. The main sign of Diabetic Retinopathy is the presence of exudates. This article demonstrates a complete framework for the detection of hard exudates in retinopathy images. This article presents the Laplacian nucleus and is induced in the spatial clustering algorithm FCM of the nucleus for the segmentation of retinal fundus images. In general, the FCM and KFCM algorithms are very sensitive to noise and other image artifacts because they have no spatial information. To overcome this problem, we present the spatial FCM of the laplacian nucleus that incorporates spatial information in its objective function and in the function of diffuse membership. The performance of our proposed algorithm was evaluated in different images of Diabetic Retinopathy. The methodology presented is evaluated using statistical measures such as Sensitivity and Specificity.
Diabetic Retinopathy is a progressive eye disease that causes changes in blood vessels in the retina that can cause blindness if not avoided and treated at an early stage. Diabetic retinopathy is one of the complications caused by diabetes and appears in the retina, which is the tissue responsible for vision in the eye. Early detection and diagnosis are essential to save the vision of diabetic patients. Indications of diabetic retinopathy on the surface of the retina are microaneurysms, haemorrhages and exudates. The identification of exudates by ophthalmologists usually requires dilation of the pupil's eye using a chemical solution that is time-consuming and affects patients. The present work investigates and presents a morphology-based techniques for the detection of diabetic retinopathy through colored fundus exudates images that includes the removal of optical disc and detected exudates are classified by means of image processing methods.
