A Multi-Orientation Analysis Approach to Retinal Vessel Tracking

Abstract: This paper presents a method for retinal vasculature extraction based on biologically inspired multi-orientation analysis. We apply multi-orientation analysis via so-called invertible orientation scores, modeling the cortical columns in the visual system of higher mammals. This allows us to generically deal with many hitherto complex problems inherent to vessel tracking, such as crossings, bifurcations, parallel vessels, vessels of varying widths and vessels with high curvature. Our approach applies tracking i… Show more

“…In our work, we rely on models of the vessels around the optic disc, made using the Edge Tracking in Orientation Scores (ETOS) algorithm [10], but in principle any model that provides the edges of vessels and detects their crossings and bifurcations can be used, for example [11,12,9]. The models are used to define an energy function (Section 2.1) that uses features extracted from both the image and the model (Section 2.2).…”

“…This brain-inspired method is based on the theory of best-fit exponential curves in the roto-translation group SE (2) developed by Duits, Franken and Janssen [15]- [17], and, importantly, does not rely on explicit segmentation of the blood vessels. 2D images are lifted to 3D functions called "orientation scores" by adding an orientation dimension to the domain [18]. In this newly extended domain of positions and orientations (identified with SE (2)), we study the exponential curves whose curvatures are constant.…”
