1. A method for performing column/row pattern suppression in a digital input image, comprising: creating a smoothed version of the input image by averaging a set of columns/rows neighboring around the column/row being corrected; constructing a difference image by subtracting the smoothed image from the input image; computing new column/row intensities from the difference image; constructing an output image with suppressed column/row patterns by subtracting the new column/row intensities from the input image.
