Testing histological images of mammary tissues on compatibility with the Boolean model of random sets
Tomáš Mrkvička, Torsten Mattfeldt
Izvirni znanstveni članek
Oznake: stereologija;rak dojke;metoda Monte Carlo;
Methods for testing the Boolean model assumption from binary images are briefly reviewed. Two hundred binary images of mammary cancer tissue and 200 images of mastopathic tissue were tested individually on the Boolean model assumption. In a previous paper, it had been found that a Monte Carlo method ...

Characterization of mammary gland tissue using joint estimators of Minkowski functionals
Torsten Mattfeldt, Daniel Meschenmoser, Ursa Pantle, Volker Schmidt
Izvirni znanstveni članek
Oznake:
A theoretical approach to estimate the Minkowski functionals, i.e., area fraction, specific boundary length and specific Euler number in 2D, and their asymptotic covariance matrix proposed by Spodarev and Schmidt (2005) and Pantle et al. (2006a;b) is applied to real image data. These two-dimensional ...

On the estimation of distance distribution functions for point processes and random sets
Dietrich Stoyan, Helga Stoyan, André Tscheschel, Torsten Mattfeldt
Izvirni znanstveni članek
Oznake:
This paper discusses various estimators for the nearest neighbour distance distribution function D of a stationary point process and for the quadratic contact distribution function Hq of a stationary random closed set. It recommends the use of Hanisch's estimator of D, which is of Horvitz-Thompson t ...
