The seismic data sections are captured with the following sequence:  Scanning. Editing heavy interpretation/annotation
marks present on the originals. Reconstruction if
necessary due to poor quality originals.On these poor quality prints optimum results are best achieved by scanning not directly to a binary file (black and white) but to an intermediate greyscale file. The greyscale file is then converted to a binary file by the Greyconv software, which uses the application of a rapidly changing, multi-dimensional dynamic threshold as well as an image filtering system. This software technique enables both light and dark areas of the same print to be successfully captured in one pass of the document. |
