Matlab 图像的采样
图像的采样
• 写程序:以2 为尺度,下采样图像 ,观察不同分辨率下图像的变化情况(a)
• 写程序:把(a)中获得的图像,进行上采样处理,可以选择不同的平滑方
法,比如,邻近像素复制,或者线性插值等。讨论上采样后图像的质量变
化。找出相应的改进方法。

LSB替换隐写
说明: LSB(英文 least significant bit)即最低有效位。LSB加密是信息隐藏中最基本的方法。由于人们识别声音或图片的能力有限,因此我们稍微改动信息的某一位是不会影响我们识别声音或图片的。(LSB replace steganography)

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.)
