Mesh free estimation of the structure model index
Joachim Ohser, Claudia Redenbach, Katja Schladitz
Izvirni znanstveni članek
Oznake:
The structure model index (SMI) is a means of subsuming the topology of a homogeneous random closed set under just one number, similar to the isoperimetric shape factors used for compact sets. Originally, the SMI is defined as a function of volume fraction, specific surface area and first derivarive ...

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 ...
