Optical coherence tomography angiography (OCTA) is a novel noninvasive
imaging modality for visualization of retinal blood flow in the human retina.
Using specific OCTA imaging biomarkers for the identification of pathologies,
automated image segmentations of the blood vessels can improve subsequent
analysis and diagnosis. We present a novel segmentation method for vessel
density identification based on frequency representations of the image, in
particular, using so-called Gabor filter banks. The algorithm is evaluated
qualitatively and quantitatively on an OCTA image in-house …
