DIARETDB1 - Standard Diabetic Retinopathy Database Calibration level 1. 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.
