基于奇异值分解的彩色图像数字水印算法

Digital watermarking algorithm for color image based on SVD

提出了一种基于奇异值分解的彩色图像数字水印算法,嵌入和提取水印均在RGB分量的空间域内进行。仿真结果表明,该算法不仅对几何失真具有很强的抵抗能力,而且对添加噪声、滤波及JPEG压缩也具有良好的鲁棒性。

This paper proposes a digital color image watermarking algorithm based on singular value decomposition （SVD）. The embedding and extracting of watermarking are finished in RGB spatial domain. Experimental results show that the watermarking method performs well in robustness, and the embedded watermark can be detected reliably, following these geometric distortions,usual processing or JPEG compression.
