GLPF-GHPF
- 在傅立叶变换域,变换系数反映了图像的某些特征。频谱的直流低频分量对应于图像的平滑区域,而外界叠加噪声对应于频谱中频率较高的部分等。 构造一个低通滤波器,使低频分量顺利通过而有效地阻止高频分量,即可滤除频域中高频部分的噪声,再经逆变换就可以得到平滑图像。-In the Fourier transform domain, the transform coefficients reflect some characteristics of the image. DC low frequency

High-Frequency-Emphasis-Filtering
- 此代码是关于高频强调滤波。利用高通滤波器削弱傅里叶变换的低频而保持高频相对不变点,这样会突出图像的边缘和细节,使得图像边缘更加清晰。但是由于高通滤波器偏离了直流分分量,从而把图像的平均值降低到了0,。一种补偿方法是给高通滤波器加上一个偏移量。通过算法达到目的。-High-Frequency Emphasis Filtering.High-pass filers zero out the DC term (the value at the center of a high-pass filter

DCT
- 基于DCT域的数字水印算法主要包括水印调制、水印嵌入和水印提取,首先在嵌入载体图像之前用Logistic混沌序列对水印进行调制,得到一个只有+1和-1随机序列的水印,同时将载体图像进行全局DCT变换,然后将水印图像嵌入人类视觉系统最重要的部分,即DCT最大的系数,DC(Direct Current)部分也包含在这最大的系数中,这部分的系数满足人类视觉特性,会使水印嵌入的性能更好。嵌入算法是将水印与这些系数进行相乘获得新的系数,再用新的系数来替换原来的系数,即获得嵌入水印后的离散余弦域的图像,然后
