Optic Disc and Optic Cup Segmentation for Glaucoma Detection
Glaucoma is an eye disease that leads to vision loss. The symptoms of the glaucoma occurs when disease is quite advance. Glaucoma is called ‘silent thief of sight’ so, that early detection of glaucoma is very essential. In existing approach three methods are used to detect glaucoma namely Assessment of raised intraocular pressure (IOP).Assessment of abnormal visual field. Assessment of damaged ...
متن کاملBoosting Convolutional Filters with Entropy Sampling for Optic Cup and Disc Image Segmentation from Fundus Images
We propose a novel convolutional neural network (CNN) based method for optic cup and disc segmentation. To reduce computational complexity, an entropy based sampling technique is introduced that gives superior results over uniform sampling. Filters are learned over several layers with the output of previous layers serving as the input to the next layer. A softmax logistic regression classifier ...
متن کاملGlaucoma Screening using Digital Fundus Image through Optic Disc and Cup Segmentation
Globally, glaucoma is the major cause of visual impairment. It is a chronic eye disease in which optic nerve damages progressively due to the raised Intraocular Pressure (IOP) of the eye. The technique proposed in this paper allows automatic detection of the glaucoma using digital fundus image by extracting the features like vertical cup to disc ratio (CDR), its area ratio, horizontal to vertic...
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 کاملClustering Based Optic Disc and Optic Cup Segmentation for Glaucoma Detection
Glaucoma is a chronic eye disease that leads to vision loss. As it cannot be cured, detecting the disease in time is important. Current tests using Intra Ocular Pressure (IOP) are not sensitive enough for population based glaucoma screening. Optic nerve head assessment in retinal fundus images is both more promising and superior. The method to segment optic disc and optic cup using Simple Linea...
