2D Fast Vessel Visualization Using a Vessel Wall Mask Guiding Fine Vessel Detection

Figure 1

(a) Original fundus image with not well-traced peripheral network. (b) Original fundus image ellipse corrected. (c) Binary vessel wall pixel map (VWP). (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) Ground troth vessel vasculature. (h) Redundant vessel vasculature produced using an Augmented VM and double-sided GS-MG. (i) Successive maps taken using different features and different sensitivity. (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.
