In this chapter, we propose a pixel adjustment procedure for digital watermarking methods using uniform color space. Many digital watermarking methods use uniform color space due to the convenience of controlling image quality (Yoshiura & Echizen, 2006). However, there is the problem that watermarked RGB integer pixel values in such methods are not quite corresponding to the watermarked real-nu...

This paper addresses the problem of automatically eliminating unwanted colour variation between similar image pairs. We propose a feature-based registration method to align colour histograms without any spatial processing of the image content or assumptions about the scene contents. We use the method for the colour transfer problem. The features are histogram maxima that persist through the sca...
