Abstract
For highlight or dark areas of images, the error terms diffused to neighborhood pixels include components which are periodic with respect to a wavelength where the wavelength is a function of the density level of the pixels from which the error terms are diffused. In this manner, patterned artifacts or 'worms' in the highlight or dark areas of the images are reduced or illuminated.
