| dc.description.abstract | Simple inverse filtering of each spectral component of a color picture can lead to serious misregistration of the restorations. This is a consequence of the nonlinearity of the photographic process, which distorts edges of objects in an unknown manner. To force three restorations that do register, we tack onto the usual term describing mean -square resemblance to the object scene the constraint of mutual resemblance among the three restorations themselves. This term is highly sensitive to phase errors (misregistrations) among its three members. The optimum three filters complying with this minimization problem are found. A simple case is examined, in order to judge the manner by which the restoring filters force a mean-square resemblance to the original object scene and, simultaneously, a mutual registration among the three restorations. | |
