彩色图像的篡改检测及自恢复算法
- 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

- 【转】针对彩色载体图像,提出了一种彩色图像超复数频域的水印算法。它通过对彩色载体图像进行快速超复数傅氏变换,在超复数频域选择合适频段嵌入水印,并且修改其对称系数的值,保证了嵌入水印图像仍然可以用彩色图像的红、绿、蓝三色进行传输。分析表明提出的方法通过超复数傅氏逆变换,可以把水印带来的误差扩散到整幅图像,并且是分散到红、绿、蓝三色的各个分量上,从而实现数字水印的不易感知性和安全性的良好结合。本算法还提出了对水印数据进行“交叉冗余嵌入”的规则,以进一步提高数字水印的鲁棒性。最后给出了实验结果,验证了
