DiaRetDB1 V2.1 - Diabetic Retinopathy Database and Evaluation Protocol


The DiaRetDB1 is a public database for evaluating and benchmarking diabetic retinopathy detection algorithms. The database contains digital images of eye fundus and expert annotated ground truth for several well-known diabetic fundus lesions (hard exudates, soft exudates, microaneurysms and hemorrhages). The original images and the raw ground truth are both available.

In addition to the data we also provide Matlab functionality (M-files) to read data (XML-files), fuse data of several experts and to evaluate detection methods.

This database is related to ImageRet project and the ground truth was collected using our ImgAnnoTool image annotation tool (contact Lasse Lensu for more information). For a more detailed description, see our documentation, please.


The following authors have significantly contributed to the actual work of establishing and collecting the data and implementing the methods for the database:
Tomi Kauppi, Valentina Kalesnykiene, Iiris Sorri, Asta Raninen, Raija Voutilainen, Joni Kamarainen, Lasse Lensu and Hannu Uusitalo.

If you find any errors or bugs, or have comments related to the database
contents, please contact the authors.


The README.txt contains a short introduction to the contents of the database.

The base functionality for reading and showing images and ground truth is included as a separate package called ddb2, download and extract it. These functionalities you can use to establish training data for your methods and for evaluating your method. See ddb2_doc for www documentation. Most importantly, after downloading the both database and ddb2 functionality run ddb2_demo1.m in order to make sure that everything works on your system!

NOTE: Do not care about our "weird" naming, i.e. ddb2 directory should be considered as "ddb1_tools". This is due to our dodgy internal version control ;-)


If you have any problems or suggestions concerning the images or ground truth please contact one of the authors.
