The former page does no longer exist, and the page you are looking at is the most current page in which the Messidor-2 database can be downloaded. The original Messidor-Original database has been established to facilitate studies on computer-assisted diagnoses of diabetic retinopathy. The research community is welcome to test its algorithms on this database.
If you are a researcher working in an academic institution, you are more than welcomed to download the database, use it, and spread the name of Messidor among your community. The Messidor-2 dataset is a collection of Diabetic Retinopathy DR examinations, each consisting of two macula-centered eye fundus images one per eye. Part of the dataset Messidor-Original was kindly provided by the Messidor program partners.
The remainder Messidor-Extension consists of never-before-published examinations from Brest University Hospital. In the original Messidor dataset, some fundus images came in pairs, some others were single. Messidor-Original consists of all image pairs from the original Messidor dataset, that is examinations images, saved in PNG format. In order to populate Messidor-Extension , diabetic patients were recruited in the Ophthalmology department of Brest University Hospital France between October 16, and September 6, Eye fundi were imaged, without pharmacological dilation, using a Topcon TRC NW6 non-mydriatic fundus camera with a 45 degree field of view.
Only macula-centered images were included in the dataset. Messidor-Extension contains examinations images, in JPG format. Overall, Messidor-2 contains examinations images. The dataset comes with a spreadsheet containing image pairing. However, some third-parties proposed such annotations, but these are independent from the official Messidor-2 database, and therefore not handled by our services. Messidor-2 can be used, free of charge, for research and educational purposes.
