Multiple Coherehence simulate using matlab

在此pdf文件里论诉了MATLAB图像合成的相关知识，并给出了其具体实现。我自己已经实现过，代码很全没有问题。(In this pdf document on the MATLAB Image Synthesis v. knowledge, and gives the concrete realization. I myself have been achieved, the code is no problem with the whole.)

说明：  基于MATLAB的FIR带阻数字滤波器的设计 由于生物医学信号处理过程中易混入50Hz噪声的特点，本文利用程序设计法和FDATool设计法，设 计一带阻滤波器，并将设计的滤波器应用到一混和正弦信号，通过测试检验，该滤波器可以很好地消除50Hz的工 频干扰。(】To prevent the biomedical signals from being disturbed by 50Hz noise easily，the paper designs a bandstop digital filter by procedure and FDATool method．The filter is tested by a blended 81ne wave experimentally and the result shows that the filter can cancel the 50Hz noise very well．)

说明：  模拟光的折射，通过经典光学拟合光路的传输(Simulation of light refraction, through fitting the classical optical transmission of optical)

My demonstration program is coded by MATLAB. For the program, some optimization at coding level and algorithm level are proposed to improve the performance of my fingerprint recognition system. These performance enhancements are shown by experiments conducted upon a variety of fingerprint images. Also, the experiments illustrate the key issues of fingerprint recognition that are consistent with what the available literatures say.

实现功率谱估计的两种方法，直接法与自相关法(Power spectrum estimation of the two methods, the direct method and the autocorrelation method)

说明：  重压缩检测：检测图像是否存在两次JPEG压缩并定位篡改区域(double JPEG detection)

双二进制信号是一种信号体制利用码间干扰作为一种控制方式而不是消除码间干扰(Duobinary signaling is a three level signaling scheme that uses intersymbol interference in a controlled way instead of trying to eliminate it. )

matlab上应用BP神经网络，预测人口、风速、温度。(Based on matlab, BP neural network to forecasting wind speed, temperature, populatioon.)
