2D Fast Vessel Visualization Using a Vessel Wall Mask Guiding Fine Vessel Detection
Figure 3
(a) Original fundus image for averagely traced major and peripheral network along with drusen. (b) Original fundus image ellipse corrected. (c) Binary vessel wall map. (d) Binary fundus image ellipse and drusen corrected. (e) Retinal vasculature with coarse and fine network based on VWP. (f) Retinal vasculature without VWP map using MIP. (g) Manually labelled ground truth vessel vasculature. (h) Redundant vessel vasculature produced using an augmented VM and double-sided GS-MG. (i) 2nd vessel network: Successive maps taken using different features and different sensitivities (thresholds). Gradient homogeneity VMs. Paired VP map and dominant gradient VM. Increased vessel width allowed, lower gradient threshold and interpolated WPs. Experimentally proved VM.
