2.2.2 Structured analysis of the retina (STARE)

We use the human retina images from the STARE database [20]. The fundus images from this database are acquired by a retinal camera TopCon TRV-50 type with a field of view 35° and which consist of 605 � 700 with 24 bits/pixel. Figure 3a shows an example of a raw image im0139.ppm, and Figure 3b shows vascular networks marked by hand provided by Valentina Kuznetsova, im0139.ah.ppm [26, 27].
