Singular values manifest image’s inherent algebraic character,which will not severely change when the image suffering a slight perturbation. The singular value decomposition and wavelet transform can be advantages of combining to achieve the compromise of digital watermarking’s robustness and invisibility.
奇异值表现了图像内在的代数特性,当图像受到轻微的扰动时,它的奇异值不会发生剧烈地改变,将奇异值分解与小波变换相结合可以优势互补,达到数字水印鲁棒性和不可见性的良好折中。
