WebAbstract: 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. WebOptical drives like CD and DVD drives read and write data from optical discs by means of a laser. The laser, emitted from a lens, reads tiny pits or marks on the surface of an optical disc, the pattern of which is then interpreted into digital data.

Optic nerve atrophy is damage to the optic nerve. Causes include poor blood flow to the eye, disease, trauma, or exposure to toxic substances. WebThe detection of optic disc is achieved using multiresolution-based normalized cross correlation technique. The detection point is used for the initialization of the active contour. Subsequent optimized evolution of the basis-spline-based active contour provides an accurate segmentation of the optic disc. We present validations on the databases ...
