Digital Image Processing With MATLAB

盲源分离EASI算法，一种简单的盲源分离算法，容易实现(Blind source separation of EASI)

说明：  高斯滤波是一种较常见的滤波方法，它能有效滤除高斯白噪声的影响。(Gaussian filter is a common filtering method can effectively filtered Gaussian white noise.)

自己的一个实验,验证频率的采样定理.即采样点数要足够大.(own an experiment to test frequency of the sampling theorem. That sampling points should be powerful enough.)

一个PCA用于人脸识别的程序，不知道有没有，先传了供大家参考下。 (a PCA for face recognition procedures, I do not know any first-of reference for everyone under.)

QPSK误码率仿真及星座图，仿真入门级。信号的调制译码(The Simulation and QPSK constellation, entry-level simulation. Decoding the signal modulation)

基于非线性主成分分析的自适应变步长盲源分离算法(Based on the nonlinear principal component analysis of adaptive variable step length blind source separation algorithm is proposed )

图像处理程序集，包含基本的图像处理MATLAB实例(Image processing assembly)

如上图所示，定向耦合器由完全相同的直波导与弯曲波导构成，波 导芯为宽高比相同（均为 a） 的正方形， 其工作波长，波导材料 对 TE 模式的折射率，及圆弧形弯曲波导的半径 r 等参数如图所 示，若波长为 1550 nm， 归一化光功率为 1 的光波从直波导输 入，请选择适当的满足单模工作的波导宽度 a， 然后给出从圆形弯 曲波导输出的归一化光功率 P4与两波导边缘的间距 d(Directional coupler by the same straight and curved waveguides constituting the waveguide, waves Conducting core is the same aspect ratio (are a) square, its operating wavelength, the waveguide material The refractive index of the TE mode and the arc-shaped curved waveguide of radius r and other parameters as shown Shown, if the wavelength of 1550 nm, normalized optical power a light straight waveguide input In, the appropriate work to meet the single-mode waveguide width a, and then is given a circular bend Curved waveguide output normalized optical power P4 and two edges of the waveguide spacing d)
