As the total number of the characters could overwhelm the capacity of a neural network, the existing OCR encoding methods pre-define a smaller set of characters that are frequently used.

Segmentation is so far the most widely investigated medical image processing task, but the various segmentation challenges have typically been organized in isolation, such that algorithm development was driven by the need to tackle a single specific clinical problem.

As part of REFUGE, we have publicly released a data set of 1200 fundus images with ground truth segmentations and clinical glaucoma labels, currently the largest existing one.
Fundoscopic images are often investigated by ophthalmologists to spot abnormal lesions to make diagnoses.
Retinal vessel segmentation is an indispensable step for automatic detection of retinal diseases with fundoscopic images.
