基于傅里叶变换的数字水印算法，在原始图像的傅里叶变换域中对称的嵌入数字水印信息(Fourier transform-based digital watermarking algorithm, the original image of the Fourier transform domain, the embedded digital watermark information symmetry)

Log Spectral Distance Signal

K-SVD可以看做K-means的一种泛化形式，K-means算法总每个信号量只能用一个原子来近似表示，而K-SVD中每个信号是用多个原子的线性组合来表示的。 K-SVD通过构建字典来对数据进行稀疏表示，经常用于图像压缩、编码、分类等应用。(K-SVD can be regarded as a generalized form of K-means. The total K-means algorithm can only approximate one signal for each semaphore, and each signal in K-SVD is a linear combination of multiple atoms To express. K-SVD through the construction of the dictionary to sparse data representation, often used for image compression, encoding, classification and other applications.)
