摘 要: 提出了一种基于SVD特性的鲁棒数字水印新算法,利用SVD分解得到U矩阵的唯一性,且图像叠加一定噪声后U矩阵的列向量失真较小这一特性,将图像自身的特征置入奇异值矩阵。实验结果表明该算法鲁棒性较好。 This paper proposes a new robust image watermarking algorithm based on SVD, using SVD the uniqueness of decomposed U matrix,Image after adding noise, the columns of the U matrix vector characteristics of less distortion,sets at into the singular value matrix image own characteristic and expenmental results show that this method is much more robust than other methods presented before.
