具有可视化界面的离散无记忆信道容量迭代计算(Visual interface with discrete memoryless channel capacity iteration)

卡尔曼滤波的理解，利用一个简单的正弦信号来进行卡尔曼滤波，从而更好的理解卡尔曼滤波。(Understanding of the Kalman filter, with a simple sinusoidal signal to the Kalman filter so as to better understand the Kalman filter.)

说明：  基于物理光学透镜成像原理，利用MATLAB语言编写了仿真程序，制作了GUI界面。(Based on the imaging principle of physical optical lens, the simulation program is written in MATLAB language, and the GUI interface is made.)

The code is a Matlab program which can be use to calculate the energy distribution of grating. The method used is RCWA method.

运用matlab实现了旋转矢量法的仿真，仿真结果表明了算法的有效性(Using matlab to achieve a rotation vector method of simulation, simulation results show the effectiveness of the algorithm)

中值滤波 原图像画面清晰，添加了椒盐噪声以后图像上出现了明显噪声，经不同模板的中值滤波处理后图像上的噪声被虑去，但使得图像变得模糊，并且，使用的模板越大，去噪声效果越好，同时图像也越模糊。滤波效果明显优于平滑滤波。 (Median filtering the original image, a clear picture of the Salt and pepper noise added after the image there is a clear noise, and by different template after median filtering has been taking into account the noise on the image to go, but makes the image become blurred, and, using the template more large, to noise, the better the effect, while the more blurred the image. Filtering effect is superior to smoothing.)

在四点星座图中，通过运用聚类的方式，实现对由于信道、噪声或其他原因出现随机偏移星座点的识别与归类。main.m为入口程序(The four-point constellation, the constellation points of the random offset due to channel noise or other reasons, through the use of clustering Identification and classification.)

QPSK的调制解调，跟书上的框图基本如出一辙，希望对大家有帮助。(QPSK modulation and demodulation, the basic block diagram of the book with the same, we want to help.)

This code is written for the map transformations, affine, conformal and polynomial. It basically uses, the parameter estimation process regarding to the quality assesment.

说明：  一个比较快速的阴影检测算法，基于HSV色彩空间(Shadow detection algorithm based on HSV color space)
