Vessel Tracking via Sub-Riemannian Geodesics on ℝ2×P1
This page contains the results of our vessel tracking experiments on retinal image patches using a sub-Riemannian geometry. We compared the model on SE(2) with the proposed model on the projective line bundle PT(R2). Details are described in the paper.
- The main article  can be found here.
A .zip file containing snapshots of all the results can be found here. The same color coding is used as in the article (Fig. 4):
- Green: SE(2) geodesic connecting the seed with the sink with forward arrival direction.
- Red-Dashed: SE(2) geodesic connecting the seed with the sink with backward arrival direction.
- Blue: PT(R2) geodesic connecting the seed with optimal arrival direction.
