A novel method for glaucoma detection using optic disc and cup segmentation in digital retinal fundus images

Abstract: Retinal fundus photographs has always remained the gold standard for evaluating the changes in retina. Here, a novel method for automatic glaucoma detection from digital retinal fundus images is proposed. The methodology makes useof optic disc and cup segmentation. Optic disc is segmented using morphological operations and hybrid level-set methodology. Optic cup is segmented by first detecting blood vessels using SVM classifier and then the bending points on the circum linear vessels. Parameters such as vertic… Show more

“…In [54], authors estimated OD center using thresholding and distance transformation technique, which was then followed by the estimation of Eigenvector spaces of normal set and glaucoma using PCA algorithm. As classifier, authors [54] applied different algorithms like Bayes classifiers [54], K-NN [50], logistic regression [55]. Authors [55] applied GLCM with linear transformation technique to perform Glaucoma detection.…”

“…However, its performance can't be generalized as the aforesaid trait might vary over one to another. In [36][37], a self assessed disc segmentation method was proposed for OD and OC segmentation [44], where deriving CDR values in the fundus image authors performed Glaucoma detection. However, the use of static CDR threshold for classification limits its generalization.…”

“…O método proposto é testado em 50 imagens, coletadas em um banco de dados, e encontrou com sucesso as amostras doentes em 48 casos com a taxa de sucesso de 96%. Jose and Balakrishnan (2015) utilizam a segmentação das regiões do disco óptico e da escavação na sua metodologia. A região do DO é segmentada usando operações morfológicas e uma metodologia híbrida.…”
