Abstract(in English) | This paper proposes a scheme of digital ghost-watermarking for color images. First we describe the basic algorithm of digital ghost-watermarking for monochrome images. Next we introduce the transformation of RGB color space into YC_bC_r color space in order to apply the algorithm to color images efficiently, and then we examine which of luminance component (Y) and chrominance components (C_b,C_r) is suitable for embedding digital ghost-watermarks. Finally by means of computer simulation for test images, we show that the watermark information in each image can be detected sensitively by our scheme even when the watermarked images are subjected to white noise, lossy coding and clipping. |
