frft
矩形信号的frft(分数傅里叶变换wigner_ville_1.m 单分量信号去噪
wigner_ville_2.m 双分量平行信号去噪
wigner_ville_3.m 3分量信号频率检测)分数傅里叶变换是经典傅里叶变换的另一种改进方式。它的主要特点是提供研究对象从时间域到频率域全过程的综合描述,随着阶数从0连续增长到1,分数傅里叶变换展示出研究对象从纯时间域逐步变化到纯频率域的所有变化特征。因此,分数傅里叶变换提供了远比傅里叶变换多得多的可供选择的数据处理和分析方法。(The rectangular signal FRFT (Fractional Fourier Transform) Score Fourier transform is another modification of the classic Fourier transform. Its main feature is a comprehensive description of the study from the time domain to the frequency domain, with the order of continuous growth from 0 to 1, the fractional Fourier transform demonstrate the object of study from a purely time-domain gradually change to a pure frequency domain variation. Thus, the fractional Fourier transform provides data processing and analysis methods than Fourier transform much more to choose from.)

SVD-based-watermarking
基于SVD的DCT域和DWT域的经典水印算法,该算法通过提取水印水印的主成分并把该主成分嵌入到奇异值矩阵,鲁邦性非常高。(the principal components of the watermark are embedded into the host image in discrete cosine transform (DCT) and for the second method, those are embedded into the host image in discrete wavelets transform (DWT). To improve the robustness, the particle swarm optimization (PSO) is used for finding the suitable scaling factors.
