“…This ridge detection method is based on the retinal vessel segmentation method [12][13][14]18]. Let us denote ( ) with = ( , ) to be the SW image, where the first derivative of the image ( ) in the direction perpendicular to the ridge tangent has a zerocrossing.…”

“…Although supervised segmentation methods (reviewed in section 2) are more competitive in terms of performance than unsupervised approaches [36] [37] [38], their dependence on ground-truth and the problem of intra-and inter-observer variability limits their robustness [34]. In this and many other fields of medical image understanding, ground truth tends to be sparse as the laborious and skilled nature of the task makes it very expensive to acquire.…”

“…Wang et al [38] proposed an unsupervised retinal vessel segmentation method that does not require a pre-processing stage. The vessels are initially enhanced using a matched filter with a multi-wavelet kernel which is capable of responding to blood vessels and non-vessel edges.…”

“…The training data or hand labelled ground truths are not needed for the design of algorithm in these approaches. These approaches are matched filter-based (Chaudhuri et al;1989;Hoover et al;Chanwimaluang and Fan;Cinsdikici and Aydın;2009;Zhang et al;Chakraborti et al;, scale space-based (Martínez-Pérez et al;Vlachos and Dermatas;Wang et al;, tracking-based , model-based (Szpak and Tapamo;Xiao et al;, adaptive thresholding-based (Jiang and Mojon;Cornforth et al;2005;Akram and Khan;, mathematical morphology-based (Zana and Klein;Mendonca and Campilho;Jiménez et al;Miri and Mahloojifar;2012a) and clustering-based (Tolias and Panas;1998;Yang et al;Kande et al;2011a,b;Sun et al;Saffarzadeh et al;. Chaudhuri et al (1989) implemented matched filter response (MFR) by initially approximating the intensity of gray-level profiles of the cross-sections of retinal vessels using a Gaussian shaped curve.…”

“…Vlachos and Dermatas (2010) proposed a retinal vessel segmentation method based on multi-scale line-tracking procedure and morphological post-processing. Wang et al (2013) proposed multi-wavelet kernels and multi-scale hierarchical decomposition. Vessels were enhanced using matched filtering with multi-wavelet kernels.…”
