在图像水印领域，研究主要集中在灰度图像水印，而对彩色情况的扩展通常通过标记图像亮度或单独处理颜色通道来完成。提出了一种基于主成分分析(PCA)的三波段RGB彩色图像数字水印方法。这项研究是我们以前工作的扩展，包括在基于PCA特征图像的彩色图像的三个RGB通道中嵌入相同的数字水印。我们评估了该方法对一些水印攻击的有效性。实验结果表明，该方法对最突出的攻击有较好的抵抗能力。
In the field of image watermarking, research has been mainly focused on gray image watermarking, whereas the extension to the color case is usually accom-plished by marking the image luminance, or by processing color channels separately. In this paper we propose a new digital watermarking method of three bands RGB color images based on Principal Component Analysis (PCA). This research, which is an extension of our earlier work, consists of embedding the same digital water-mark into three RGB channels of the color image based on PCA eigenimages. We evaluated the effectiveness of the method against some watermark attacks. Exper-imental results show that the performance of the proposed method against most prominent attacks is good.
