On Optimal Color Coordinate Selection for Wavelet-Based Color Image Watermarking

摘要

In ubiquitous multimedia applications, color images are the basic components of multimedia systems. Although many research has been devoted to develop proper watermarking procedures using multiresolution-based transformation, most of these investigations faced the watermarking problem from a gray scale point of view. In this paper, different color spaces which commonly used to represent color images are tested and compared for wavelet-based data hiding approaches in order to find the best candidate with respect to robustness and transparency of the final watermarked image.
