Minimal Paths and Geodesic Metrics for Image Segmentation and Tubular Structure ExtractionMS43

We solve two drawbacks of the classical minimal path models. Firstly, the curvature term was removed in the model in order to transform the problem into finding distance map associated to a source point. We reintroduce the curvature term to the Eikonal PDE framework to find curvature regularised minimal paths. Moreover, in the context of segmentation, existing metrics depend only on object boundary information. We propose a new Finsler metric involving the region-based similarity/dissimilarity measure.
