Image Database
The images in the STARE database are designated imXXXX where XXXX is a four digit number. The available images are numbered from 0001 to 0402. Five numbers in this range are missing. Of the 397 available images, 43 images have missing or incomplete annotations or ground truth diagnoses, as listed in Table 1. In these cases the expert physician felt that the image was impossible to diagnose alone (a physician might use verbally acquired evidence from the patient, as well as multiple images of multiple portions of the patient's eye in order to conclude a diagnosis). The remaining 354 images with annotations were used for experiments in this thesis.

Table 1. Incomplete annotations or ground truth diagnoses

We define these 354 images according to four categories. A familiar image has all its ground truth diagnoses within the set of thirteen recognizable diagnoses. An unfamiliar image has all its ground truth diagnoses outside the set of thirteen recognizable diagnoses. A partially familiar image has at least one of its ground truth diagnoses outside the set of thirteen recognizable diagnoses and at least one of the ground truth diagnoses within the set of thirteen recognizable diagnoses. A normal image exhibit no disease. Tables 2-5 list the images according to these four categories.
