Reducing halo artifacts in electrophotographic printing systems

A method for reducing halo artifacts in an electrophotographic printing system, the method implemented at least in part by a data processing system and comprising:

• receiving an input image including a plurality of input pixels having input pixel values;
• automatically analyzing the input image 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;
• performing 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 thereby providing expanded light-side edge regions;
• forming a corrected image 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;
• and
• printing the corrected image using the electrophotographic printing system.
