说明：  该代码实现了车牌的定位，利用matlab实现，效果很少而且鲁棒性也很好(The code to achieve the positioning of the plate, using matlab to achieve results and very few good robustness)

这是一个低通抽样定理，例题中包括了低通信号的波形，抽样速率为4Hz的抽样信号，抽样序列恢复出原始信号(This is a low-pass sampling theorem, examples included in the lowpass signal waveform, the sampling rate is 4Hz sampling signal to recover the original signal sample sequence)

matlab 实现的基于logistic 混沌映射的图像加密，可用于灰度图像和彩色图像的加密。(Grayscal and color image encryption based on Logistic map)

说明：  VAD matlab程序 常见于无声帧检测 语音信号处理(VAD matlab program is commonly used in silent frame detection speech signal processing)

说明：  灰度传递函数分析，(a)高斯传递模型，(b)和(c)分别是理想编码图经过结构光系统前后的灰度分布，(d)和(e)分别是编码图和采集图。(Gray transfer function analysis, (a) Gaussian transfer model, (b) and (c) are the ideal coding picture through structured light system before and after gray level, (d) and (e) are coded map and chart collection .)
