Messidor-2

Introduction

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.

Messidor-2 Dataset

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.

Using the database

Messidor-2 can be used, free of charge, for research and educational purposes. Copy, redistribution, and any unauthorized commercial use are prohibited. Any publication relying on this dataset must acknowledge the LaTIM laboratory and the Messidor program partners.
