Pseudo-color engraving-prints using signal processing methods

In this contribution we propose an application for pseudo-color engraving-prints. Usually, the prints that are made with relief and intaglio techniques, are black and white images composite by a group of binary lines. Several texture and gray levels are obtained changing direction and density of lines in the print. We propose an application based signal processing methods to pseudo-color black and white prints. The proposed method can be done in real time using a white light optical correlator. The different color channels R, G and B could be encode simultaneously using a color film for filter representation. In this way the pseudo-color processing can be done in one cycle of the optical processor.
