Abstract
A method for removing artifacts from a bitmap of image data produced by scanning a halftone image may comprise the steps of: (a) calculating a weighted average intensity value for a target pixel based on a weight factor for the target pixel and on weight factors for neighboring pixels in the bitmap of image data; (b) repeating step (a) for each pixel in the bitmap of image data; and (c) replacing the intensity value of each pixel in the bitmap of image data with the weighted average intensity value for each such pixel.
