Mean values for homogeneous stit tessellations in 3D
Werner Nagel, Viola Weiss
Izvirni znanstveni članek
Oznake:
Recently (Nagel and Weiss, 2005), the class of homogeneous random tessellations that are stable under the operation of iteration (STIT) was introduced. In the present paper this model is reviewed and new results for the mean values of essential geometric features of STIT tessellations in two and thr ...

Miles formulae for boolean models observed on lattices
Joachim Ohser, Werner Nagel, Katja Schladitz
Izvirni znanstveni članek
Oznake:
The densities of the intrinsic volumes - in 3D the volume density, surface density, the density of the integral of the mean curvature and the density of the Euler number - are a very useful collection of geometric characteristics of random sets. Combining integral and digital geometry we develop a m ...

The Euler number of discretised sets - surprinsing results in three dimensions
Joachim Ohser, Werner Nagel, Katja Schladitz
Izvirni znanstveni članek
Oznake:
The problem of estimating the Euler-Poincare characteristic (Euler number for short) of a set in the 3d Euclidean space is considered, given that this set is observed in the points of a lattice. In this situation, which is typical inimage analysis, the choice of an appropriate data-based discretisat ...

A tessellation model for crack patterns on surfaces
Werner Nagel, Joseph Mecke, Joachim Ohser, Viola Weiss
Izvirni znanstveni članek
Oznake:
This paper presents a model of random tessellations that reflect several features of crack pattern. There are already several theoretical results derivedwhich indicate that thismodel can be an appropriate referencemodel. Some potential applications are presented in a tentative statistical study.
