Fresnel diffraction

过滤图像.平均过滤，中值过滤，自适应过滤。(Filtered image average filter, median filter, adaptive filter.)

计算时频图，功率图的程序，运用在matlab里面。可以很好的实现图形(Computing time-frequency map, power map program, use the matlab inside. Can achieve a good graphics)

说明：  涡旋光束干涉图样计算程序，采用matlab编写的涡旋光束干涉图样计算程序。(The program of vortex beam interference pattern is compiled by MATLAB.)

Transforming images from the spatial domain to frequency domain using FFT and DCT, also it includes transforming to the Cepstrum domain.

说明：  典型的SAR回波模型，对初学者还可以。大家可以下载下来调试一下(A typical SAR echo model, beginners can also)

利用小波分解与重构,实现图像滤波和压缩,可灵活选用其他小波,简单易懂,特别适合小波初学者.(using wavelet decomposition and reconstruction, image filtering and compression, the flexibility to choose other wavelet is simple to understand and Wavelet particularly suitable for beginners.)

Matlab, Laser, Hermite polynomals, m-file

omp算法，该编码通俗易懂，应用简单。用于求压缩感知中，在字典D已知的前提下，一个信号在该字典上的稀疏表示。(omp algorithm, and compressed sensing, sparse representation of a signal in the dictionary in the dictionary D known premise.)

基于递推原理的RLS线性阵列算法，入门很好的学习资料！(RLS based on the principle of recursive linear array algorithms, data entry good learning!)

利用Ford--Fulkerson 标号法求最大流算法的MATLAB 程序代码 (Use Ford- Fulkerson labeling method for maximum flow algorithm MATLAB code)
