Abstract

We propose a Fast Marching based implementation for com-
puting sub-Riemanninan (SR) geodesics in the roto-translation group
SE(2), with a metric depending on a cost induced by the image data.
The key ingredient is a Riemannian approximation of the SR-metric.
Then, a state of the art Fast Marching solver that is able to deal with
extreme anisotropies is used to compute a SR-distance map as the so-
lution of a corresponding eikonal equation. Subsequent backtracking on
the distance map gives the geodesics. To validate the method, we con-
sider the uniform cost case in which exact formulas for SR-geodesics are
known and we show remarkable accuracy of the numerically computed
SR-spheres. We also show a dramatic decrease in computational time
with respect to a previous PDE-based iterative approach. Regarding im-
age analysis applications, we show the potential of considering these data
adaptive geodesics for a fully automated retinal vessel tree segmentation.
