Effects of modeling domains on recursive color image restoration

Image restoration techniques such as the Reduced Update Kalman Filter, are usually applied to monochromatic images, but can also be applied to the components of color images. It is of interest to consider and compare the restoration of density and intensity representations of the corresponding color components to determine the representation which results in the best restoration. Based on experiments with photographic and simulated blurs, it was concluded that in general, images should be restored in the intensity domain.
