Abstract:
1. An image processing method for transforming a selected portion of an initial color digital image received from a computer operable scanner into digital image objects with enhanced halftone edges for output in a computer print engine comprising: a) selecting a target color pixel location within the initial color digital image received from a computer operable scanner; b) observing a set of color pixels within a pixel observation window superimposed on the initial color digital image, relative to the target pixel location; c) generating, through use of a computer processor, edge-state codes for a plurality of pairs of neighboring vectors of pixels within the pixel observation window; d) generating, through use of the computer processor, using a computer architecture edge-identification codes from the plurality of edge-state codes using at least one look-up table wherein the edge-state codes are generated by and wherein the edge-identification codes indicate proximity to a tinted edge; and, e) transforming the edge-identification codes and the initial color digital image at the target color pixel into a halftone screen comprised of at least one of:
