Abstract:
We propose to apply a marked point process to detect a galaxy filament
network. From the ``Quality Candy'' model, initially developed for road
network extraction in remotely sensed images, we adapt the data term to
the filament detection. The optimization is realized by a simulated
annealing using a Reversible Jump Markov Chain Monte Carlo algorithm.
Results are presented on a numerical simulation and on an astronomical
survey.
