Abstract

Color images degraded by defocusing and chromatism are restored using different digital models and linear filtering techniques. The restoration process for color images is properly performed through the filters associated with three transfer functions for tristimulus values. However, the use of three monochromatic OTFs corresponding to the maxima of the color receiver is also discussed for different cases of wavelength-dependent aberrations, since it enables a significant reduction in the computer processing time.
