摘    要:随着图像技术的快速发展,当信息内容涉及到政治、军事、商业、法庭举证等重要数据时,其真实性和完整性必须得以确认。提出一种结合Zernike矩的半脆弱水印算法,利用图像小波变换低频子带的Zernike矩幅值的半脆弱特性区分恶意攻击和偶然攻击,提高了水印的安全性.并能准确地定位出篡改区域。

关 键 词:Zernike矩  半脆弱水印  图像认证

Abstract:With the rapid development of the image techniques,If the image contains important data,such as politics,military,commerce and evidence,the authenticity and integrality of the image must be validated.In this paper,a semi-fragileim watermarking algorithm using Zernike moments is proposed,it can distinguish malicious modification from incidental modification according to semi-fragile characteristics of zernike moments of the low frequency subband in the integer wavelet transform domain of an image,improving w...
Keywords:Zernike moments  semi-fragile  image authentication
