瑞利衰落信道（Rayleigh fading channel）是一种无线电信号传播环境的统计模型。这种模型假设信号通过无线信道之后，其信号幅度是随机的，即“衰落”，并且其包络服从瑞利分布。(Rayleigh fading channel (Rayleigh fading channel) is a radio signal propagation environment, the statistical model. The model assumed that after the signal through the wireless channel, the signal amplitude is random, that is, " fading" and subject to its Rayleigh distribution envelope.)

matlab环境下编写的fft算法实现的源代码(prepared environment matlab algorithm fft source code)

详细介绍了当前常用的配准方法，比较实用。(image-registion optical flow)

数字图像跟踪，可以计算应力应变，对数字图像研究很有用(Compilation of .m files to calculate strain from images independent of physical size of the samples. Strain can be calculated in horizontal as well as vertical direction. The functions were developed at the Johns Hopkins University by Rob Thompson, Daniel Gianola and me, all of us part of the Group of Kevin Hemker. Dan is now at the UPenn (http://gianola.seas.upenn.edu) and I am now at the Karlsruhe Institute of Technology (http://www.yin.kit.edu/?id=57, Germany) and will continue to work on the code. Sven Bundschuh just entered the authors guild and provided a new grid_generator.m and some essential changes. )
