This paper studies the restoration of color quantized images. Restoration of color quantized images is rarely addressed in the literature, and direct applications of existing restoration techniques are generally inadequate to deal with this problem. We propose a restoration algorithm specific to color quantized images, which makes a good use of the available color palette to derive useful a priori information for restoration. The proposed restoration algorithm is shown to be able to improve the quality of a color quantized image to a certain extent.
