Microaneurysms detection in color fundus images using machine learning based on directional local contrast [PDF]

BioMedical Engineering OnLine, 2020
Background As one of the major complications of diabetes, diabetic retinopathy (DR) is a leading cause of visual impairment and blindness due to delayed diagnosis and intervention. Microaneurysms appear as the earliest symptom of DR.

EARLY DIAGNOSIS OF DIABETIC RETINOPATHY BY THE DETECTION OF MICROANEURYSMS IN FUNDUS IMAGES [PDF]

ICTACT Journal on Image and Video Processing, 2018
The detection of microaneurysms is crucial, as it is an early indicator of a complication of prolonged diabetes called Diabetic Retinopathy. In this paper, an automated approach is proposed to detect microaneurysms from retinal fundus images.

A Method for Diagnosing Diabetic Retinopathy Based on Ocular Fundus Imaging

Известия высших учебных заведений России: Радиоэлектроника, 2022
Introduction. Diabetic retinopathy is a complication of diabetes mellitus caused by high blood sugar levels damaging the retina. Diabetic retinopathy leads to changes in ocular blood vessels and the appearance of solid exudates and microaneurysms.

An Enhanced Residual U-Net for Microaneurysms and Exudates Segmentation in Fundus Images

IEEE Access, 2020
Diabetic retinopathy (DR) is a leading cause of visual blindness. However if DR can be diagnosed and treated early, 90% of DR causing blindness can be prevented significantly. Microaneurysms (MAs) and exudates (EXs), as signs of DR, can be used for early

A Novel Diabetic Retinopathy Detection Approach Based on Deep Symmetric Convolutional Neural Network

IEEE Access, 2021
Diabetic Retinopathy (DR) may lead to blindness in diabetic patients, which is one of the most severe eye diseases. Therefore, using automatical technology to detect DR at the early phase has very vital clinical significance.
