2D Fast Vessel Visualization Using a Vessel Wall Mask Guiding Fine Vessel Detection
Figure 2
(a) Original fundus image with well traced major network and slightly distinct major peripheral network. (b) Original fundus image ellipse corrected. (c) Binary vessel wall map. (d) Vessel map based on VWP. (e) Retinal vasculature based on VWP and fine-segmented for local details. (f) Retinal vasculature without VWP map using MIP. (g) Estimated 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). (A) Gradient homogeneity VMs. (B) Paired VP map and dominant gradient VM. (C) Increased vessel width allowed, lower gradient threshold and interpolated WPs. (D) Experimentally proved VM.
