刚刚完成的一个用Matlab实现画中画的功能，代码简洁，很实用！代码+仿真结果！(Just completed implementation of a PIP function with Matlab, the code is simple and it works!)

93C66 application notes

计算图像PSNR，非常高效的源码，具有一定的参考价值。(Calculated image PSNR, very efficient source, with some reference value.)

信号与系统实验(高级) 实验六 电话拨号音的合成与识别(Signals and Systems Experiment (advanced) experiments six telephone dial tone Synthesis and Recognition)

：滤波 fs=400 采样频率,必须大于两倍基带信号最高频率 ts=1/fs 采样时间间隔 T=5 时间窗大小 t=0:ts:T (hf1=zeros(1,N) hf1(f<=B1&f>=-B1)=1 y1=hf1.*fftshift(y) figure subplot(211) plot(f,abs(fftshift(y))/N,f,hf1, r-- ) axis([-fs/2,fs/2,0,1.2]) title( 原信号频谱 ) xlabel( f /Hz ) subplot(212) plot(f,abs(y1)/N) title( 低通滤波，截止频率90Hz ) xlabel( f /Hz ))

will be very useful for those who need code for lsb steganography

基本的PSO程序，可以直接运行。希望大家喜欢。(basic PSO)

新手学习MATLAB画图很好的例子，程序直接复制到MATLAB中就可以运行。(MATLAB drawing newcomers to learn a good example, be copied directly into MATLAB programs can run.)

krige插值，主要用于地统计学的科学计算，从国外网站找到。(interpolation krige ，kriging，cokriging)
