Abstract

Most color image printing and display devices do not have the capability of reproducing true color images. A common remedy is the use of dithering techniques that exploit the lower sensitivity of the eye to spatial resolution and exchange higher color resolution with lower spatial resolution. In this paper an adaptive error diffusion method is presented. The error diffusion filter coefficients are updated by a normalized LMS type algorithm to prevent textural contours, color impulses and color shifts which are among the the most common side effects of the standard dithering algorithms
