说明：  基于肤色的人脸检测，肤色的提取。基于肤色的人脸检测方法，包括肤色模型建立和肤色分割过程两大部分内容。在比较了颜色空间和两种模型后，选择了在 YCbCr 空间建立高斯模型。输入图像经过相似度计算、阈值分割、最后得到人脸区域。-(matlab color detection procedure. rgb2tsl.m color model used for conversion, will be converted to RGB mode TSL model. realize skin.m color detection, color region is white, non-color region is black.)

所谓跳频，比较确切的意思是：用一定码序列进行选择的多频率频移键控。(The so-called frequency hopping, the exact meaning is: a certain code sequence selected frequency to frequency shift keying.)

粒子群算法,自己编的一个程序，可以实现，运行main函数(Particle Swarm Optimization)

在自适应噪声对消中的，周期信号和噪声信号的分离，利用了噪声延时后的非相关性。(In the adaptive noise canceller, the periodic signal and the noise signal separation, the use of the noise delayed non-correlation.)

这是一个关于基于VCSOA的光开关的仿真程序。仿真程序基于传输矩阵法设计的，将整个器件在轴向按折射率的不同分成很多层。计算了在外部抽运（即泵浦，加在放大器上的工作电流）呈现周期性变化时，放大器将输出一系列的光脉冲，即光开关。 ( This is a simulation package for computing the characteristics of the VCSOA when acting as an optical switch, which is designed based on TMM( transfer matrix method). The whole device is splitted into many segments in the axis direction according to different index. When the external pump is a periodic signal, the output of the VCSOA would be a pulse train, which can be used as optical switch. )
