ABSTRACT:
A method for digitizing seismic traces comprising optically digitizing the seismic sections to produce a digitized image, normalizing the digitized image for brightness to produce a normalized digitized image, geometrically straightening the digitized image, and recovering the negative portions of said seismic traces to produce a fully restored wave form of the digitized image.
