Reconstruction de volume de particules basée sur un processus à la Tomo-PIV
2015
In this paper, we propose a new tomographic reconstruction method, called IOD-PVRMPP, to reconstruct 3D particle volumes
from 2D particle images provided by the Tomographic Particle Image Velocimetry (Tomo-PIV) technique. Our method, based on marked point
processes (or object processes), allows to solve the problem in a parsimonious way and facilitates the introduction of prior knowledge. To this
aim, we use a simulated annealing algorithm based on Reversible Jump Markov Chain Monte Carlo (RJMCMC) method. To speed up the
convergence of the simulated annealing, we develop an initialization method. Using synthetic data, we show that IOD-PVRMPP method gives
better results than MinLOS-MART method for different seeding densities.
