Laplace2D

主动轮廓模型（蛇模型）及应用MATLAB源码，(Active Contour Model (Snake Model) and application of MATLAB source,)

模拟2个独立窄带信号分别以20°，60°的方向入射到均匀线阵上，信号间互不相关，与噪声相互独立，噪声为理想高斯白噪声，阵元间距为入射信号波长的1／2，快拍数为200，信噪比为20dB，阵元数分别为10，50，100。 (Simulate two independent narrowband signals in the direction of 20 °, 60 ° of the incident on the ULA, among signal unrelated, independent noise, the noise is ideal Gaussian white noise, the array element spacing of the incident signal wavelength of 1/2, the number of snapshots 200, SNR is 20dB, the array element number 50, 100, respectively.)

kalman来控制摄像头的运动，比较容易看懂的算法(kalman filter is used to control the camera)

说明：  OpenCV库的Matlab函数封装调用 cvlib_mex封装了OpenCV库大约30个函数，OpenCV是当前流行的实时计算机视觉库，拥有很多的图像处理的算法。(cvlib_mex is a collection (over two dozens) of matlab callable routines from the OpenCV library www.intel.com/research/mrl/research/opencv/). OpenCV is a real time computer vision library with many image processing capabilities and it is amazingly fast as well as economic.)

子程序，将QAM符号向量d0_J映射为二进制符号矩阵gry(Subroutines, will QAM symbol vector d0_J the mapping matrix for the binary symbols gry)

两本PDF格式电子书，是关于s-function编写的。内容很全面。(Two PDF format e-books, is about the s-function written. Content is very comprehensive.)

说明：  通过步进电机的数学模型对二相步进电机进行仿真，并通过卡尔曼滤波处理数据，最终通过处理后的数据预估两相步进电机的相电流和相电压。(The mathematical model of the stepping motor is used to simulate the two-phase stepping motor, and the data are processed by Kalman filter. Finally, the phase current and phase voltage of the two-phase stepping motor are predicted by the processed data.)

我们设计低通数字滤波器并选择窗函数确定频率响应。(We design a digital low pass filter and the choice of window function to determine the frequency response. )
