In this thesis we propose two methods for optic disc (OD) localization in scanning laser ophthalmoscope (SLO) images. The methods share a locating phase, while differ in the OD segmentation. We tested the algorithms on a pilot of 50 images (1536x1536) from a Heildelberg SPECTRALIS SLO camera, annotated by four expert ophthalmologists. The second algorithm performs better than the first one achieving accuracy of 90%. We compared also our methods with a validated OD algorithm on fundus images.

Abstract
In this thesis we propose two methods for optic disc (OD) localization in scanning laser ophthalmoscope (SLO) images. The methods share a locating phase, while differ in the OD segmentation. We tested the algorithms on a pilot of 50 images (1536x1536) from a Heildelberg SPECTRALIS SLO camera, annotated by four expert ophthalmologists. The second algorithm performs better than the first one achieving accuracy of 90%. We compared also our methods with a validated OD algorithm on fundus images.File in questo prodotto:
