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 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 ...
