Pchannel_resampling

这是matlab从runlenth code 中译码 并指纹提取的源码 一个m文件 三张 指纹图像文件(This is runlenth code in matlab from the decoding and extracting the source fingerprint of a document m 3 fingerprint image files)

This code is about short time fourier transform.

file dll special for the file spike under matlab code.
