基于贝塞尔-傅里叶矩的零水印算法
A Zero Watermarking Based on Bessel-Fourier Moments
摘要
Abstract
The existing color image watermarking method based on spatial domain has no resistance to geometric transformation. If the color image is rotated by little angles, the watermark could not be detected. In order to improve the accuracy of the embedding watermark and the ability to resist rotation geometric transformation, a zero watermarking algorithm based on Radon transform and re⁃al matrix of quaternion is proposed. Firstly, the real matrix of quaternion is used to represent the original color image, and then the Bessel-Fourier invariant moments of the real matrix is calculated. Finally, some low orders Bessel-Fourier invariant moments are used to design and construct zero watermarking information. The experiment results show that this proposed method can obtain better visual effect, and it is robust enough to rotation attack. Meanwhile, it is also robust enough to some mage degradation process such as filtering, JPEG compression and cropping attack.关键词
