1. A seismic modeling system comprising: a seismic model data storage device; and a processor cooperating with said seismic model data storage device to transform a seismic model spatial domain data set associated with a given region into a seismic frequency domain data set, the given region including a suspect region, transform a seismic model spatial domain data subset associated with the suspect region into a seismic frequency domain data subset, perform inpainting of the seismic frequency domain data subset based upon the seismic frequency domain data set, convert the inpainted seismic frequency domain data subset into an inpainted spatial domain data subset, substitute the inpainted spatial domain data subset for the seismic model spatial domain data subset associated with the suspect region in the seismic model spatial domain data set associated with the given region to generate an inpainted seismic model spatial domain data set, and store the inpainted seismic model spatial domain data set in the seismic model data storage device.
