Feature-extraction-of-finger-vein

zero crossing feature extraction

nearestSPD works on any matrix, and it is reasonably fast. As a test, randn generates a matrix that is not symmetric nor is it at all positive definite in general.

几个指向性的程序源码，包含线阵，，面阵与带加权的阵型 (Several directional program source code contains a linear array, planar array with weighted formation)

in this project we develop a source code in matlab which take attendance automatically, The source code and data base are available in this file

pso_pmu_118_bus example

神经计算的实验作业。用principle components analysis计算模式的主分量。提取线性输入的特征。(Neural computing experiment operations. Computing model using principle components analysis of the principal component)

光纤仿真,用于阶跃光纤建模,参数可另外设定(Fiber simulation for step-index fiber modeling parameters can be set separately)

移动通信系统中的维特比编码器的实现程序代码。(The codes of Viterbi Coder for mobile communication.)

Audio Feature Extraction routine. this routine extracts the attack time of an audio source, by extracting the timing (sample) of the highest peak. The archive inclues a routine to extract the fft and display it. Requires Voicebox for matlab.

雷达信号处理中的CFAR仿真程序，同时比较了在相同虚警率下的理想检测门限、单元平均CFAR检测门限、审核式CFAR检测门限、有序统计CFAR检测门限。(this is a program about cfar in radar signal processing。)
