DIARETDB0 - Standard Diabetic Retinopathy Database

Calibration level 0


This is a public database for benchmarking diabetic retinopathy detection from digital images. The main objective of the design has been to unambiguously define a database and a testing protocol which can be used to benchmark diabetic retinopathy detection methods. By using this database and the defined testing protocol, the results between different methods can be compared. For more information refer to the documentation.

The current database consists of 130 color fundus images of which 20 are normal and 110 contain signs of the diabetic retinopathy (hard exudates, soft exudates, micronaneuyrysms, hemorrhages and neovascularization). Images were captured with a 50 degree field-of-view digital fundus camera with unknown camera settings. The data correspond to practical situations, and can be used to evaluate the general performance of diagnosis methods. This data set is referred to as "calibration level 0 fundus images".
