this file contains the medical image processing. Here, I have to find the preprocessing methods. In this implementation i have to add the salt and pepper noise.

卡尔曼滤波是一种高效率的递归滤波器(自回归滤波器), 它能够从一系列的不完全包含噪声的测量(英文:measurement)中，估计动态系统的状态。(Kalman filter is an efficient recursive filter (autoregressive filter), which can contain from a series of incomplete measurement of noise (in English: measurement) is estimated dynamic system state.)

压缩感知算法重建方法：凸优化算法CVX。此方法构建具有很好的稳定性。(Compressed sensing algorithm reconstruction methods: convex optimization algorithm CVX. This method has a good build stability.)

置信传播是一中很有效的算法，将其应用于检测，通过在检测与译码之间迭代交换传递信息，并有选择地通过单边消息传递来更新信息，降低系统实现的复杂度。 (Belief propagation is a very efficient algorithm to be applied to the detection, the information transmitted by the exchange between the iterative detection and decoding, and to update the information, to reduce the complexity of system implementation is selectively transmitted through unilateral messages.)

灰度图转换，可以把彩色图片转换为灰度图片。并进行计算(Grayscale conversion, color images can be converted to gray-scale image. And calculated)

说明：  这些MATLAB的M文件分为两部分：程序清单A中收录了产生PPM-TH和PAM-DS这两个信号源的所有函数；程序清单B中收录了加性高斯白噪声（AWGN）信道建模，正交和非正交单脉冲PPM-TH接收机结构，以及反极性PAM-DS单脉冲接收机结构仿真所需的所有函数。(The MATLAB M-file is divided into two parts: A list of procedures in the collection of produce PPM-TH and PAM-DS two signal sources all functions Listing B, contains an additive white Gaussian noise (AWGN) channel construction mode, orthogonal and non-orthogonal single-pulse PPM-TH receiver structure, as well as anti-polarity PAM-DS receiver structure simulation of single-pulse all the necessary functions.)

UKF滤波,可实现一个采样时间内的不敏（无迹）kalman滤波(UKF filter)

这个身重要，基于matlab的三维时域有限差分程序（UPML各向异性的完美匹配吸收层），使学习时域有限差分方法的好资料。(The body important matlab-based three-dimensional finite difference time domain procedures (UPML anisotropic perfectly matched layer), enabling learners to FDTD good information.)

说明：  有关于S函数的，滑模变结构例程3,内涵simulink和m函数(Learning about the S function, SMVSC routine 3)
