The monitoring of the effects of retinopathy on the visual system
can be assisted by analyzing the vascular architecture of the
retina. This book presents methods based on Gabor filters to detect
blood vessels in fundus images of the retina. Forty images of the
retina from the Digital Retinal Images for Vessel Extraction
(DRIVE) database were used to evaluate the performance of the
methods. The results demonstrate high efficiency in the detection
of blood vessels with an area under the receiver operating
characteristic curve of 0.96. Monitoring the openness of the major
temporal arcade (MTA) could facilitate improved diagnosis and
optimized treatment of retinopathy. This book presents methods for
the detection and modeling of the MTA, including the generalized
Hough transform to detect parabolic forms. Results obtained with 40
images of the DRIVE database, compared with hand-drawn traces of
the MTA, indicate a mean distance to the closest point of about
0.24mm. This book illustrates applications of the methods mentioned
above for the analysis of the effects of proliferative diabetic
retinopathy and retinopathy of prematurity on retinal vascular
architecture.
