Active contour method for ILM segmentation in ONH volume scans in retinal OCT

Kay Gawlik, Frank Hausser, Friedemann Paul, Alexander U. Brandt & Ella Maria Kadas
The optic nerve head (ONH) is affected by many neurodegenerative and autoimmune inflammatory conditions. Optical coherence tomography can acquire high-resolution 3D ONH scans. However, the ONH's complex anatomy and pathology make image segmentation challenging. This paper proposes a robust approach to segment the inner limiting membrane (ILM) in ONH volume scans based on an active contour method of Chan-Vese type, which can work in challenging topological structures. A local intensity fitting energy is added in...
