1 April 2008Detection of blood vessels in the retina with multiscale Gabor filters
We propose image processing techniques for the detection
of blood vessels in fundus images of the retina. The methods
include the design of a bank of directionally sensitive Gabor filters
with tunable scale and elongation parameters. Forty images of the
retina from the Digital Retinal Images for Vessel Extraction database
were used to evaluate the performance of the methods. The results
of blood vessel detection using inverted green-channel images were
compared with the corresponding manually segmented blood vessels.
High efficiency in the detection of blood vessels with the area
under the receiver operating characteristics curve of up to 0.96 was
achieved with a combination of Gabor filters at three scales.
