Retinal blood vessels segmentation using classical edge detection filters and the neural network
Informatics in Medicine Unlocked, 2021 Retinal blood vessels analysis is of interest for medical screening, especially in the diagnosis of diabetic retinopathy. In this paper, we propose a new method for the segmentation of blood vessels in retinal photographs.

Evaluation of Nonperfused Retinal Vessels in Ischemic Retinopathy [PDF]
Investigative Ophthalmology and Visual Science, 2016 Purpose: Retinal ischemia has been traditionally assessed by fluorescein angiography, visualizing perfused vessels. However, this method does not provide any information about nonperfused vessels, and although it is often assumed that vessels in ischemic

Scale-aware dense residual retinal vessel segmentation network with multi-output weighted loss [PDF]
BMC Medical Imaging, 2023 Background Retinal vessel segmentation provides an important basis for determining the geometric characteristics of retinal vessels and the diagnosis of related diseases. The retinal vessels are mainly composed of coarse vessels and fine vessels, and the

Retinal Vessels Segmentation Based on Dilated Multi-Scale Convolutional Neural Network [PDF]
IEEE Access, 2019 Accurate segmentation of retinal vessels is a basic step in diabetic retinopathy (DR) detection. Most methods based on deep convolutional neural network (DCNN) have small receptive fields, and hence they are unable to capture global context information ...
