A sharpness dependent filter for mesh smoothing
Chen C., Cheng K. Computer Aided Geometric Design 22(5): 376-391, 2005. Type: Article
Mesh representation is commonly used to represent the surfaces of three-dimensional (3D) objects. When an object is represented as a computer readable file (for example, by laser scanning), the values captured may be subject to numerical noise...

Accurate optical flow computation under non-uniform brightness variations
Teng C., Lai S., Chen Y., Hsu W. Computer Vision and Image Understanding 97(3): 315-346, 2005. Type: Article
In this paper, the authors revise a former approach from Horn and Schunck’s and Lai and Vemuri’s framework to compute optical flow. Horn and Schunck’s regularization gradient-based method’s drawbacks relate mainly to the...

Applications of smoothing methods in numerical analysis and optimization
Chen X. In Focus on computational neurobiology. Commack, NY: Nova Science Publishers, Inc., 2004. Type: Book Chapter
This chapter presents an overview of the use of smoothing methods for addressing various approximation optimization problems for which the objective function F(x) is nonsmooth. In this context, “smooth” means...

Additive and multiplicative multi-grid--a comparison
Bastian P., Hackbusch W. (ed), Wittum G. Computing 60(4): 345-364, 1998. Type: Article
Many variants of multigrid have been developed. In this paper, the authors present a comparative study of additive and multiplicative multigrid. They also investigate the behavior of multigrid variants with respect to smoothing, which plays an...

Constrained smoothing of histograms by quadratic splines
Schmidt J. (ed) Computing 48(1): 97-107, 1992. Type: Article
The standard histospline problem for a histogram F =  f 1 ,..., f n  on a mesh &Dgr; = x 0 < x 1 < ... < x n involves...

Blending algebraic surfaces
Warren J. ACM Transactions on Graphics 8(4): 263-278, 1989. Type: Article
If two surfaces are implicitly defined by the polynomials A and B, and two curves g and h on the surfaces are implicitly defined by the auxiliary polynomials G and H, then a surface implicitly defined by...

Automatic parameterization of rational curves and surfaces IV: algebraic space curves
Abhyankar S., Bajaj C. ACM Transactions on Graphics 8(4): 325-334, 1989. Type: Article
In earlier papers, the authors described algorithms from algebraic geometry for determining the genus of a plane curve and for obtaining a rational parametrization of the curve when its genus is zero. These results are of great value in...

Conditions for tangent plane continuity over recursively generated B-spline surfaces
Ball A., Storry D. ACM Transactions on Graphics 7(2): 83-102, 1988. Type: Article
The authors study some properties of surfaces which can be constructed by iteratively “knocking off” corners of an arbitrary polyhedron. Various versions of this recursive subdivision technique were proposed and evaluated by Catmull...

Smoothing surfaces using reflection lines for families of splines
Kaufmann E., Klass R. Computer-Aided Design 20(6): 312-316, 1988. Type: Article
This paper describes a method for smoothing surfaces that has been used successfully to improve the quality of outer skin surfaces in automobile body design. The method involves smoothing reflection lines and then interpolating back to determine...

Discrete smooth interpolation
Mallet J. ACM Transactions on Graphics 8(2): 121-144, 1989. Type: Article
This paper gives a method for constructing a grid of points from scattered data; in the examples, though, the author assumes that the data points are a subset of the grid points. The grid values minimize a certain discrete pseudonorm; this...
