一种基于DWT-SVD的彩色图像水印嵌入方法

Research on the Color Image Watermarking Embedded Method Based on SVD-DWT Domain

摘要: 为了进一步加强多媒体的信息安全和版权保护问题,文中基于离散小波变换和奇异值分解理论,提出将RGB三色通道的水印图像分别嵌入到载体RGB三色通道中,其特点是以彩色图像作为水印.实验结果表明,该算法水印具有不可见性好、嵌入信息量大、抗攻击能力强等特点.

Abstract: In this paper, based on discrete wavelet transform and singular value decomposition theory, we embedded RGB waterwark image in colour image.The experiment results indicate that the algorithm is characteristic of high time efficiency, good quality for watermarked image, large amount of information and excellent robustness.
