Exudate segmentation in fundus images using an ant colony optimization approach
The leading cause of new blindness and vision defects in working-age people, diabetic retinopathy is a serious public health problem in developed countries. Automatic identification of diabetic retinopathy lesions, such as exudates, in fundus images can contribute to early diagnosis. Currently, many studies in the literature have reported on segmenting exudates, but none of the methods performs...
متن کاملBlood Vessels Segmentation from Fundus Eye Images Using Mathematical Morphology
In this paper the new method for automatic segmentation of blood vessels from fundus eye images is proposed. The proposed method is composed of the following steps; 1) contrast enhancement, 2) denoising, 3) vessels detection, 4) classification.
متن کاملOptic disc segmentation for glaucoma screening system using fundus images
Segmenting the optic disc (OD) is an important and essential step in creating a frame of reference for diagnosing optic nerve head pathologies such as glaucoma. Therefore, a reliable OD segmentation technique is necessary for automatic screening of optic nerve head abnormalities. The main contribution of this paper is in presenting a novel OD segmentation algorithm based on applying a level set...
متن کاملModel Based Segmentation for Retinal Fundus Images
This paper presents a method for detecting and measuring the vascular structures of retinal images. Features are modelled as a superposition of Gaussian functions in a local region. The parameters i.e. centroid, orientation, width of the feature are derived by a minimum mean square error (MMSE) type of spatial regression. We employ a penalised likelihood test, the Akakie Information Criteria, t...
متن کاملBlood Vessel Segmentation in Retinal Fundus Images
The segmentation of retinal blood vessels in the retina is a critical step in diagnosis of diabetic retinopathy. In this paper, we present a new method for automatically segmenting blood vessels in retinal images. Five basic algorithms for segmenting retinal blood vessels, based on different image processing techniques, are described and their strengths and weaknesses are compared. A hybrid alg...
