Abstract
In this paper, we present a novel algorithm that extracts feature curves from triangular mesh domains. It is an extension of the level-set formulation of active contour model in image space to triangular mesh domains. We assume that meshes handled by our method are smooth overall, and feature curves of meshes are thin regions rather than mathematical curves such as found in mechanical parts. We use a simple and robust scheme that assigns feature weights to the vertices of a mesh. We define the energy functional of the active contour over the domain of triangular mesh and derive a level-set evolution equation that finds feature regions. The feature regions are skeletonized and smoothed to form a set of smooth feature curves on the mesh.
