1. A system comprising:
a processor; and
a non-transitory computer-readable medium comprising instructions that are executable by the processor to cause the processor to perform operations comprising:
receiving a velocity model for a geological area of interest;
applying a dynamic filter to the velocity model for smoothing an anomaly included in the velocity model, wherein a shape of the dynamic filter is variable with respect to absolute depth; and
applying the velocity model with the smoothed anomaly to seismic data associated with the geological area of interest for converting a domain of the seismic data.
