Description: 彩色图像的篡改检测及自恢复算法赵春晖,孙建军,朱海峰(哈尔滨工程大学信息与通信工程学院,黑龙江哈尔滨150001)摘要:数字水印是图像认证的有效手段之一.利用小波变换提出一种计算简单的彩色图像水印算法,将一个图像的主要内容嵌入该图像自身之中,用均值量化的方法在亮度信号中嵌入水印,实现篡改检测和定位篡改区域;用多余的色度空间嵌入亮度信号和色度信号,用于恢复被篡改的图像内容.该算法可以获取较高的峰值信噪比,具有很好的鲁棒性.实验结果表明,该算法对删除、替换等恶意图像篡改具有良好的检测、定位和自修复能力.-color image tamper detection and self-recovery algorithm Zhao Chunhui, Sun Jianjun, Zhu Haifeng (Harbin Engineering University, Information and Communication Engineering Institute, Harbin, Heilongjiang 150001) Abstract : digital watermark image authentication is one of the effective means. Using wavelet transform A simple calculation of the color image watermarking algorithm, an image of the main elements embedded in the image itself, and use of quantitative methods mean the luminance signal embedded watermark, achieve tamper detection and localization tampering with the region; use of surplus space embedded color luminance signals and chrominance signals, for the restoration of tampering with the image content. The algorithm can generate a higher signal-to-noise ratio of the peak value, h Platform: |
