Automatic Optic Disc Segmentation Based on Modified Local Image Fitting Model with Shape Prior Information

Table 1

Performance measurement based on overlapping areas between different initial contours on the DIARETDB0 database and the DRISHTI-GS database.

Initial contour	Accuracy rate (DIARETDB0) (%)	Accuracy rate (DRISHTI-GS) (%)
Contour intersecting the OD	94.50	94.10
Contour within the OD	94.80	94.50
Contour outside the OD	95.10	95.30
Adaptive contour	96.30	96.10
