GNGTS 2018 - 37° Convegno Nazionale

586 GNGTS 2018 S essione 3.1 Time Migration (RTM) over the entire data. In this scenario, the input is a depth migrated image obtained from a very coarse acquisition geometry; the output is the corresponding depth migrated image as obtained with a dense acquisition geometry. The dataset is a modified version of the SEG/EAGE Overthrust model; we extracted 1392 pairs of patches from 58 2D-migrated in-lines and x-lines. Each 2D section was made of 768x128 samples, with a sampling step of 30 meters. The coarse data have been generated by migrating a coarse geometry of 10 equispaced sources and 80 equispaced receivers; the fine Fig. 1. Fig. 2.
