<b>Introduction</b>
<p>UoA-DR database is created as part of the research being carried
out at the University of Auckland aimed at developing an automatic screening
system to screen patients affected by Diabetic Retinopathy (DR). This database
was developed in collaboration with three hospitals in India Al-Salama Eye
hospital, Dr. Tony Fernandez Eye Hospital, and Giridhar Eye Institute. The
database consists of 200 retinal images mostly affected with diabetic
retinopathy.</p>
<p>This database also
contains the manually segmented features. These are: retinal vessels, optic
discs and fovea, which can be used as a ground truth for other retinal image
processing algorithms. Also, for each image in this database, the optic disc
center and fovea center locations are identified manually. Medical diagnosis is
provided for each image based on guidelines provided by the International
Clinical Diabetic Retinopathy scale.</p>
<p> </p>
<p><b>Contents of the Database</b></p>
<p>The following materials are included in the database</p>
<p>Retinal images: 200 images taken by Fundus camera </p>
<p>Images resolution: 2124 x 2056 pixels </p>
<p>Extracted features: 3 per image (Retinal Vessels, Optic disc
boundary and center, Fovea center location) </p>
<p>Excel files: 2 (DR Classification and OD Fovea Index)</p>
<p>PDF file: 1 (UoA-DR diabetic retinopathy severity classification.pdf)</p>
<p>Database size ≈ 500MB</p>
