Geometric Splines and Interpolation on S2: Numerical Experiments
Proceedings of the 45th IEEE Conference on Decision and Control, 2006Several different procedures are presented to produce smooth interpolating curves on the two-sphere S2. The first class of methods is a combination of the pull back/push forward technique with unrolling data from S2 into a tangent plane, solving there the interpolation problem, and then wrapping the resulting interpolation curve back to the manifold ...

A geometric criterion for smooth interpolation of curve networks
2009 SIAM/ACM Joint Conference on Geometric and Physical Modeling, 2009A key problem when interpolating a network of curves occurs at vertices: an algebraic condition called the vertex enclosure constraint must hold wherever an even number of curves meet. This paper recasts the constraint in terms of the local geometry of the curve network.

Image interpolation using multiscale geometric representations
SPIE Proceedings, 2007With the ever increasing computational power of modern day processors, it has become feasible to use more robust and computationally complex algorithms that increase the resolution of images without distorting edges and contours. We present a novel image interpolation algorithm that uses the new contourlet transform to improve the regularity of ...

Least eccentric ellipses for geometric Hermite interpolation
Computer Aided Geometric Design, 2012A new solution to the geometric Hermite interpolation problem is proposed using rational Bézier ellipses. The presented method reproduces circles and the regular ellipses are reproduced by ellipses with minimal eccentricity. The computational performances of the proposed solution are revealed in a theorem that provides a method to determine the weight ...

Generalized geometric interpolation for rational cubic splines
Computers & Graphics, 1994A description and analysis of an interpolatory rational cubic spline curve is made for use in computer graphics. The generalized rational cubic pieces are stitched together with a most general form of continuity. The parameters in the description of rational cubics as well as the geometric continuity provide a variety of shape control.
