Abstract

This paper proposes a
hybrid method that is capable of automatically implementing the Optic Disc (OD)
segmentation. In the hybrid method, two steps were performed. First, the
location of the OD was determined by template matching. Second, the OD location
coordinates obtained in the first stage were given as inputs to the Active
Contour Method applied to complete the OD segmentation. Furthermore, as part of
this study,  Android based a program was
developed to allow physicians the ability to independently access the proposed
hybrid method results from anywhere and to add comments. Thus, the physician
would be able to instantly track the patient. Performance evaluation of the
proposed hybrid method was done separately for both localization and
segmentation. The success of localization was confirmed on the basis of whether
the determined coordinates corresponded to the OD. The segmentation process was
assessed according to the parameters, as derived from a confusion matrix. The
average Dice coefficient obtained for all images was 0.943, while the average
values of accuracy, specificity and sensitivity parameters for all images were
calculated as 0.90, 0.961 and 0.931, respectively. The final results obtained
from the proposed hybrid method were checked by a physician, who observed that
the OD was successfully segmented.
