Niharika Thakur,Mamta Juneja +1 more
TL;DR: Various segmentation approaches used by different researchers for optic disc followed by the optic cup and its classification for diagnosis of glaucoma are analyzed to address various research gaps and challenges.
Journal ArticleDOI
Classification of glaucoma using hybrid features with machine learning approaches
Niharika Thakur,Mamta Juneja +1 more
TL;DR: A new set of reduced hybrid features derived from structural and nonstructural features to classify the retinal fundus image, which could serve as a second opinion for ophthalmologists are presented.
