Determination of signicant color map

This paper propose an approach to extract the most significant color information that takes into account 1) the inherent sensitivity of the Human Visual System (HVS) to color variations and 2) the sensitivity of the HVS to specific colors of a given image. By giving higher importance to the significant colors in the stabilization control formulation, it is possible to retain the consistency of only the most significant colors to a human viewer. Such restriction is critical due to the limited actuation authorities of typical xerographic color printing process. To account for color-specific sensitivity, we make use of the CIE L*a*b* color formulation. To account for the image-specific sensitivity, we make use of the fact that the HVS have lower sensitivity to high frequency components (detail) of high chrominance image. Moreover, typically "smooth" images are visually more irrelevant compared to textured and detailed images. These effects in the color and spatial domain are taken into account to reduce the redundancy in the image representation by following similar procedure to that used in wavelet transform coding decomposition.
