AbstractIn this article, we consider restoring a single‐color image from two degraded frames of the same scene by a RGB sensor and a luminance sensor. The RGB‐to‐YIQ transformation, the classical Tikhonov regularization and the Neumann boundary condition are used in the restoration process. Regularization based on generalized cross‐validation function with multisensors is also used to obtain the high‐quality restored image. The resulting method is shown to provide improved restoration over other restoration methods. © 2003 Wiley Periodicals, Inc.
