When you pick semblance peaks from a velocity spectrum (velocity analysis) to determine the moveout velocity function, you implicitly make a judgment as to what is primary and what is multiple. When you pick a coherency semblance spectrum (model with low-relief structure) to determine the interval velocity profile, you make a judgment as to what degree of lateral velocity variations needs to be honored. These are but two examples of interpretive work involved in processing and inversion of seismic data, respectively.
