MATLAB做的不错的人脸识别的程序，希望大家能受用，谢谢(color)

通过计算短时信号熵，与阈值比较，得到判决结果。并采用顺序统计滤波器（最大值滤波器）对所得熵值滤波，提高判决精度。 能有效的分辨出语音信号和噪声信号，且通过后端平滑处理，使语音检测结果更加集中。(VAD based on short-time entropy, precision improved by using order-statistical-filter, VAD result is smoothed to make the result more accurate.)

模糊控制一级线性倒立摆系统MAtlab、simulink仿真(A linear inverted pendulum fuzzy control system MAtlab, simulink simulation)

Inspired with scramble game in android, a algorithm for searching dictionary words based on the traversing of 4x4 word matrix. taking long time to run but a novice idea.

WVD变换的matlab工具包，非常有用的信号时频分析工具(WVD transform matlab toolkit, a very useful time-frequency analysis tool)

利用MATLAB实现了跳频信号的调制和解调，给出了频谱图。(The use of MATLAB implementation of the frequency hopping signal modulation and demodulation, give the frequency spectrum.)

简单的Dijkstra求最短路的MATLAB程序，很好用，对于两点之间最短距离。(Dijkstra' s shortest seek simple MATLAB program, useful for the shortest distance between two points.)

对运动声目标进行航迹跟踪，并通过粒子滤波去除航迹估计值的噪声成份。(Sports sound track to track targets and, through the particle filter to remove the estimated value of track noise component.)
