SUMMARY: (...): C. Coiffard (IRMA\\\, Unistra): A Markov point process for 
 Fiber extraction
DESCRIPTION:: A Markov point process for Fiber extraction\nBy Claire Coiffa
 rd\\\, IRMA\\\, Unistra.\n\n\nAbstract:\nThe aim of this work is to extrac
 t fibers in an image. We use a stochastic modelisation of the image : an o
 bservation is a realisation of a marked process. Using a bayesian approach
 \\\, we define our estimator by a MAP criterion. The model used to define 
 the density of our process is the Gibbs process. The energy associated is 
 divided into two parts : an internal field that favors specific spatial st
 ructures and the external field that quantifies the quality of the configu
 ration with respect to the data. The problem of optimization is solved by 
 a simulated annealing and MCMC methods.
