Image Database

The database consists of 110 colour digital retinal images. Initially, it were obtained 124 eye fundus images selected randomly from an eye fundus image base belonging to the Ophthalmology Service at Miguel Servet Hospital, Saragossa (Spain). From this initial image base, all those eye images (14 in total) that had some type of cataract (severe and moderate) were eliminated and, finally, was obtained the image base with 110 images.

Table 1 shows, for the 110 images selected, all those visual characteristics related to potential problems that may distort the detection process of the papillary contour. The mean age of the patients was 53.0 years (S.D. 13.05), with 46.2% male and 53.8% female and all of them were Caucasian ethnicity. 23.1% patients had chronic simple glaucoma and 76.9% eye hypertension. The images were acquired with a colour analogical fundus camera, approximately centred on the ONH and they were stored in slide format. In order to have the images in digital format, they were digitised using a HP-PhotoSmart-S20 high-resolution scanner, RGB format, resolution 600x400 and 8 bits/pixel.

Ground truth

Independent contours from 2 medical experts were collected by using a software tool provided for image annotation. A person with medical education and solid experience in ophthalmology was considered as an expert. In each image, each expert traced the contour by selecting the most significant papillary contour points and the annotation tool connected automatically adjacent points by a curve. As expected, there was an inter-observer variability among the two experts tracing the contour of a papilla. For this reason, in our work [1] we used as a gold stantard, in each image, the average of the contours traced by the two experts. From here, it can be downloaded the ground truth of the each expert.
