This database has been established by a collaborative research group to support comparative studies on automatic segmentation algorithms on retinal fundus images. The database will be iteratively extended and the webpage will be improved.
We would like to help researchers in the evaluation of segmentation algorithms. We encourage anyone working with segmentation algorithms who found our database useful to send us their evaluation results with a reference to a paper where it is described. This way we can extend our database of algorithms with the given results to keep it always up-to-date.

The database can be used freely for research purposes. We release it under Creative Commons 4.0 Attribution License. If you are using our database to evaluate your methods, please cite

• Segmentation Dataset

  The public database contains at the moment 15 images of healthy patients, 15 images of patients with diabetic retinopathy and 15 images of glaucomatous patients. Binary gold standard vessel segmentation images are available for each image. Also the masks determining field of view (FOV) are provided for particular datasets. The gold standard data is generated by a group of experts working in the field of retinal image analysis and clinicians from the cooperated ophthalmology clinics. We intend to add further gold standard data to the existing images to help the evaluation of algorithms which localize the macula, optic disc, or differentiate between arteries and veins.

  Image Quality Assessment Dataset

  We captured 18 image pairs of the same eye from 18 human subjects using a Canon CR-1 fundus camera with a field of view of 45° and different acquisition setting. For each pair, the first image has poor quality and thus the examination had to be repeated. Both images share approximately the same field of view, whereas small shifts were caused by eye movements between the acquisitions.
  
  In the current version of our database, images of poor quality suffer from decreased sharpness (locally or globally), e.g. due to a defocused camera. Further quality features (e.g. image contrast or illumination conditions) may be considered in a future version. The available dataset was captured by Jan Odstrcilik.
