Optic Nerve Head Segmentation [PDF]

IEEE Transactions on Medical Imaging, 2004
Reliable and efficient optic disk localization and segmentation are important tasks in automated retinal screening. General-purpose edge detection algorithms often fail to segment the optic disk due to fuzzy boundaries, inconsistent image contrast or missing edge features.

Advances in MRI optic nerve segmentation [PDF]

Multiple Sclerosis and Related Disorders
Understanding optic nerve structure and monitoring changes within it can provide insights into neurodegenerative diseases like multiple sclerosis, in which optic nerves are often damaged by inflammatory episodes of optic neuritis. Over the past decades, interest in the optic nerve has increased, particularly with advances in magnetic resonance ...
