说明: 本文提出了一种基于混沌加密的DCT域二值图像数字水印算法.该算法首先利用混沌序列将含有版权信息的有意义二值图像水印进行加密,然后利用人眼视觉系统(HVS)的特性将原始载体图像进行块分类,最后将不同强度的水印分量嵌入到不同类的图像块DCT中频系数中去.利用混沌序列对水印进行加密,使水印本身具有安全性,对数字作品进行双重保障.通过高斯噪声,椒盐噪声以及JPEG压缩和剪切等攻击试验,表明了该算法具有较好的鲁棒性.(Encryption in DCT domain is proposed. Firstly, the meaningful binary image watermark containing copyright information is encrypted by using chaotic sequence, and then the original image is classified by using the characteristics of human visual system (HVS), Finally, the watermark components with different intensities are embedded into the DCT intermediate frequency coefficients of different types of image blocks. Chaotic sequences are used to encrypt the watermark, so that the watermark itself has security and double protection for digital works. Experiments on Gaussian noise, salt and pepper noise, JPEG compression and clipping show that the algorithm has good robustness)

1.灰度变换:选择一幅对比度不足的图像,对该图像进行灰度变换,增强对比度,显示增强前、后的图像以及它们的灰度直方图。
2.直方图均衡:选择一幅灰度直方图不均匀的图像,对该图像进行直方图均衡处理,显示处理前、后的图像以及它们的灰度直方图。
3.选择一幅边缘较模糊的图像,利用高通滤波器(选择或自己设计)对该图像进行边缘增强,观察增强的效果。
4.选择一幅图像,叠加零均值高斯噪声,分别利用低通滤波器、维纳滤波器和中值滤波器对该有噪图像进行滤波,显示滤波后的图
