Abstract
A method for processing an input image to reduce halo artifacts in an electrophotographic printing system. The input image is automatically analyzed to determine an edge map image indicating light-side edge regions that include edge pixels that are adjacent to edge transitions in the input image and are on a lighter side of the edge transition. At least one edge region dilation operation to the edge map image to expand the light-side edge regions in a direction away from the edge transitions. A corrected image is formed by modifying the input pixels of the input image corresponding to the expanded light-side edge regions to determine corrected pixels having corrected pixel values. The corrected image is then printed using the electrophotographic printing system.
