ENHANCEMENT OF MULTIPLE COLOR IMAGES WITHOUT COLOR SEPARATION ERROR BY INVERSE SYMMETRICAL TEMPLATE MATCHING |
摘要 |
A method for enhancing the contour fidelity of printed images of two or more colors is described, which includes obtaining a digital representation of the color image and finding color separations of each color. Each color separation is enhanced by a single set of inverse symmetrical templates, the set including templates in which the second template is always the inverse of the first, and the third and fourth templates are 180 degree rotations of the first two. The resulting smoothed color separations are recombined into an enhanced image without separation error.
