Model selection for the Dubuc-Deslauriers family of subdivision schemes (2013)
Presentation / Conference Contribution
Mustafa, G., & Ivrissimtzis, I. (2013, September). Model selection for the Dubuc-Deslauriers family of subdivision schemes. Presented at 14th IMA Conference on Mathematics of Surfaces, Birmingham, England

We propose two methods for model selection for the DubucDeslauriers family of subdivision schemes. In particular, we study model selection under the statistical method of cross-validation and the geometric method of minimizing the absolute discrete t...

Spectral representations of vertex transitive graphs, Archimedean solids and finite Coxeter groups (2013)
Journal Article

In this article, we study eigenvalue functions of varying transitionprobability matrices on finite, vertex transitive graphs. We provethat the eigenvalue function of an eigenvalue of fixed highermultiplicity has a critical point if and only if the co...

Linear Correlations between Spatial and Normal Noise in Triangle Meshes (2013)
Journal Article
Yang, Y., Norbert, P., & Ivrissimtzis, I. (2013). Linear Correlations between Spatial and Normal Noise in Triangle Meshes. IEEE Transactions on Visualization and Computer Graphics, 19(1), 45-55. https://doi.org/10.1109/tvcg.2012.106

We study the relationship between the noise in the vertex coordinates of a triangle mesh and normal noise. First, we compute in closed form the expectation for the angle  between the new and the old normal when uniform noise is added to a single ver...
