A properly preprocessed image of a colored scene can be used with conventional coherent correlators to recognize and locate colored patterns. Color information is encoded by means of gratings with different orientation, frequency and amplitudes. This codification permits to process polychromatic images in parallel with a monochromatic correlator.
