A POTTS MODEL FOR SEGMENTATION AND (2009)

V. Liebscher, G. Winkler

Abstract In the Bayesian framework, a (generalized) Potts prior for segmentation and piecewise smoothing of noisy signals and images is adopted. For one-dimensional signals, an exact solution for the...

Segmentation of Time Series: Parameter Dependence of Blake-Zisserman and Mumford-Shah Functionals and the Transition from Discrete to Continuous (2008)

A. Kempe, V. Liebscher, G. Winkler, O. Wittich

The paper deals with variational approaches to the segmentation of time series into smooth pieces, but allowing for sharp breaks. In discrete time, the corresponding functionals are of...

Springer Verlag, 1999 Reviewed for Metrika (2007)

Gibbs Elds, Monte Carlo Simulation, G. Winkler

Markov processes serve as mathematical models in applied sciences since the beginning of the 20th century. A main reason is their conceptual simplicity. Nevertheless, as a rst approximation to...

Complexity Penalised M-Estimation: Fast Computation (2005)

F. Friedrich, A. Kempe, V. Liebscher, G. Winkler

We present fast algorithms for the exact computation of estimators for time series, based on a simple variational approach. The functionals behind are complexity penalised loglikelihood- or...

Emergency management in the early phase (2004)

Crick, M., McKenna, T., Buglova, E., Winkler, G., Martincic, R.

An overview of response management in the early phase of an emergency at a nuclear installation is provided from a systems approach. This starts with the recognition of response goals, and using...

Smoothers for discontinuous signals (2002)

G. Winkler, V. Liebscher, V. Aurich

First we explain the interplay between robust loss functions, nonlinear lters and Bayes smoothers for edge-preserving image reconstruction. Then we prove the surprising fact that maximum posterior...

Smoothers for discontinuous signals (2002)
