... the image to the classification mask, the proposed network takes the previous mask output, together with the seismic image in a new FoV, as a combined input to predict the mask at this FoV. The movement of the FoV is guided by the flood-filling algorithm in order to visit and segment the full extent...

... Summary In migration velocity analysis (MVA), the residual moveout in the image gather is used to obtain velocity correction parameters. In this work we propose a numerical approach to describe the moveout in the image gather considering a dipping reflector instead of using approximations. We...

... for sampling this posterior distribution is Markov chain Monte Carlo (MCMC), which involves making proposals and calculating their acceptance probabilities. However, for large-scale problems, MCMC is prohibitevely expensive as it requires many forward runs. In this paper, we propose a multilevel MCMC algorithm...
