Approaches for early detection of glaucoma using retinal images: A performance analysis
Sarhan, Abdullah; Rokne, Jon; Alhajj, Reda (Springer Science and Business Media Deutschland GmbH, 2020)Sight is one of the most important senses for humans, as it allows them to see and explore their surroundings. Multiple ocular diseases damaging sight have been detected over the years such as glaucoma and diabetic ... -
Glaucoma detection using image processing techniques: A literature review
Sarhan, Abdullah; Rokne, Jon; Alhajj, Reda (Elsevier, 2019)The term glaucoma refers to a group of heterogeneous diseases that cause the degeneration of retinal ganglion cells (RGCs). The degeneration of RGCs leads to two main issues: (i) structural changes to the optic nerve head ... -
H-OCS: A hybrid optic cup segmentation of retinal images
Sarhan, Abdullah; Rokne, Jone; Alhajj, Reda (Springer Science and Business Media Deutschland GmbH, 2021)Glaucoma is the second leading cause of irreversible vision loss. Early diagnosis and treatment can, however, slow the progression of the disease. Specialists making this diagnosis rely on several tests and examinations ... -
Transfer learning through weighted loss function and group normalization for vessel segmentation from retinal images
Sarhan, Abdullah; Rokne, Jon G.; Alhajj, Reda; Crichton, Andrew C.S. (Institute of Electrical and Electronics Engineers Inc., 2021)The vascular structure of blood vessels is important in diagnosing retinal conditions such as glaucoma and diabetic retinopathy. Accurate segmentation of these vessels can help in detecting retinal objects such as the optic ... -
Utilizing a responsive web portal for studying disc tracing agreement in retinal images
Sarhan, Abdullah; Swift, Andrew J.; Gorner, Adam T.; Rokne, Jon G.; Alhajj, Reda; Docherty, Gavin; Crichton, Andrew C.S. (Public Library of Science, 2021)Glaucoma is a leading cause of blindness worldwide whose detection is based on multiple factors, including measuring the cup to disc ratio, retinal nerve fiber layer and visual field defects. Advances in image processing ... -
Utilizing digitized surveys for data collection: The case of developing countries
Sarhan, Abdullah; Addam, Omar; Rokne, Jone; Alhajj, Reda (Springer Science and Business Media Deutschland GmbH, 2021)A major concern for public and private organizations worldwide is to ensure that its constituents are healthy. However, the degree to which this is ensured differ from country to country and even from community/individual ... -
Utilizing transfer learning and a customized loss function for optic disc segmentation from retinal images
Sarhan, Abdullah; Al-Khaz’Aly, Ali; Gorner, Adam; Swift, Andrew J.; Rokne, Jon G.; Alhajj, Reda S.; Crichton, Andrew C.S. (Springer Science and Business Media Deutschland GmbH, 2021)Accurate segmentation of the optic disc from a retinal image is vital to extracting retinal features that may be highly correlated with retinal conditions such as glaucoma. In this paper, we propose a deep-learning based ...
