In addition to the industry standard semblance velocity analysis, TGS has a structural autopicker. 

This application performs a dense automatic velocity analysis and picking using the initial functions, picked by humans, as guide functions.  In either 2D or 3D the software selects the best velocity within a user-defined variance from the original guide functions.  The output velocities are then smoothed as RMS and interval velocity grids as well as Time-Velocity (TV) pairs.  An option to define the water-bottom time and velocity is also incorporated in the application.  A dense grid of high quality profiles is produced.  This process can be applied to large datasets, as well as regions of complex geology and topography.  The algorithm is able to correctly determine velocity in the complicated case of sudden dip changes near the water bottom.
