This page is the official redirection of a previous page that was available at the following url: http://latim.univ-brest.fr/indexfce0.html. 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 529 examinations (1058 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, 2009 and September 6, 2010. 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 345 examinations (690 images, in JPG format).
Overall, Messidor-2 contains 874 examinations (1748 images). The dataset comes with a spreadsheet containing image pairing. It does not contain annotations such as a diabetic retinopathy “ground truth”. However, some third-parties proposed such annotations, but these are independent from the official Messidor-2 database, and therefore not handled by our services.
