Bayesian Eikonal Tomography

MAIN FEATURES OF THE FORMULATION

• forward problem

  -- Solver for calculating first arrival times using the eikonal equation.
  
  -- Isotropic acoustic medium
  

• Numerical characteristics:

  -- Finite Difference Method (using Sethian's method to calculate arrival time)
  

• Backward problem -- Inverse problem solving to generate a velocity model set by the reversible jump Markov chain Monte Carlo method - RJ-MCMC.
