Here is some simple Matlab image warping code that I wrote a while ago that others continue to find useful. The code requires that you have Matlab and the Image Processing Toolkit installed

demonstrates the compressive sensing using a sparse signal in Time domain. The signal consists of a UWB (Ultra Wide Band) pulse in time domain. The signal is sparse in Time domain and therefore K random measurements are taken in Frequency domain.

这是一个关于fiber tracking的源程序(This is a source of fiber tracking)

设计一个模拟信号（几个不同频率简谐信号之和，再加一个白噪声） 用不同的采样频率把信号离散（满足和不满足采样定理）， 画出信号波形； 分别作信号的谱分析（幅值）；对比采样频率的影响； 选用不同窗函数对同一个信号作谱分析，比较分析。(signal process using matlab)
