Claim One:
1. A method of reducing artifacts in a digital radiographic image comprising: identifying either a row or column direction for the artifacts in the image data as a predominant direction; obtaining a measurement of the image data frequency content that is subject to the artifacts from the image content according to the predominant direction; testing the measurement of image data frequency content subject to the artifacts according to a predetermined threshold; and reducing the artifacts when the predetermined threshold is exceeded by: generating one or more suppression factors according to the testing results; decomposing the image content into at least two frequency bands in each row and column direction; applying the one or more suppression factors to modify at least one of the frequency bands; and recomposing the image content by recombining the at least one modified frequency band with one or more other bands into which the image had been decomposed.
