这是我编的一个乘子法的MATALB程序，大家看一下，还有什么需要改进的(This is Part I of a multiplier method MATALB program, we look at what needs to be improved)

compute active contour model

主要是利用归一化的方法进行位场边界识别，利用导数与周围最大值的比值来进行。(Mainly using the method of normalized potential field boundary identification, the use of derivative and the ratio of maximum to be around.)

运用matlab，LBP分割脸部特征，从而达到识别人物面部表情的效果(Use matlab, LBP split facial features, so as to identify the effect of facial expressions)

Matlab code for finding SNR

说明：  语音信号处理分析，数字图像处理系统，对输入系统的图像及语音加噪去噪(Speech signal processing)

matlab实用程序百例,都是常用程序。(matlab utility 100 cases, are commonly used procedures.)

QPSK调制与解调，并有误码率的分析，加了 信道噪声。(QPSK modulation and demodulation, and bit error rate analysis, the addition of channel noise.)

REMOVAL OF IMPULSE NOISE USING TRIMMED MEDIAN FILTER

采用两发一收的空时分组码经过瑞丽信道后的性能仿真。(The use of a collection of two space-time block codes through Ruili performance after channel simulation.)
