Digital Image Watermarking Scheme with Pseudo-Zernike Moments
一种可有效抵抗几何攻击的鲁棒图像水印算法

Pseudo-Zernike moments consist of a set of orthogonal and complex number moments which have some very important properties,shch as invariantation under rotation,multilevel representation,and less sensitivity to noise.A new robust digital image watermarking scheme with pseudo-Zernike moments was proposed.Firstly,the pseudo-Zernike moments of the host image were computed.Secondly,some low-level pseudo-Zernike moments were selected.Finally,the digital watermark were embedded into the host image by quantizing t...
