Paper Abstract

This paper discusses a method to neutralize the influence of printed colors using the additive color mixing model. The method is developed for Picture Illusion by Overlap, an image hiding method for printed materials which requires no computation in revealing the hidden image. In Picture Illusion by Overlap, a color image is hidden into two different color images. When the two images are printed onto slides and stacked together, the hidden image appears to the viewers' eyes. The color neutralization enables the image hiding operation by reducing the influence of the hidden pixels within the two images. Some experiments are made to verify the effect of the color neutralization method and the illusion scheme.
