Piecewise smooth reconstruction of normal vector field on digital data
We propose a novel method to regularize a normal vector field defined on a digital surface (boundary of a set of voxels). When the …

Curvature estimation along noisy digital contours by approximate global optimization
In this paper, we introduce a new curvature estimator along digital contours, which we called global min-curvature (GMC) estimator. As …
