Download the file town .jpg, which is a 1024×768, 256-grayscale image taken on a bright sunny day. The image was taken in the shadow of a building. As the result, the sunlight areas are glaring white and the shadow areas are dark and low contrast. Using the image enhancement techniques covered in class, increase the contrast and the brightness of the dark areas, and reduce the brightness of the sunny areas

高斯信道下采用RS 卷积码，译码时采用软硬两种判决方法对误码率进行仿真，利用simulink搭建模块，在利用m文件编程调用产生最终结果。(The paper use the RS code in AWGN.And two different of demodem way are used in it.)

MATLAB 惯导程序 里面有许多有用的程序，自己看吧，不会让你失望的(MATLAB inertial navigation procedures There are many useful program, oneself see, won t let you down )

对于参数估计问题,克拉美罗界(简称CRB)为任何无偏估计量的方差确定了一个下限. 即不可能求得方差小于下限的无偏估计量,并为比较无偏估计量的性能提供了一个标准. 本程序对CLRB（克拉美罗下界）进行了描述，预留了参数。 希望能对同志们提供帮助。(For the parameter estimation problem, Cramer-Rao bound (referred to as CRB) for any unbiased estimator of variance to determine a lower limit that can not be obtained is less than the minimum variance unbiased estimator and unbiased estimator for comparing the performance of provides a standard procedure for this CLRB (Cramer-Rao lower bound) for a description of the reserved parameters. Hoping to help comrades.)

利用matlab simulink建立了卫星姿态控制系统模型，可以通过改变控制器等参数实现对卫星的控制(Satellite attitude control system was established based on the matlab simulink model, can be realized by changing the controller parameters, such as control of the satellite )

The purpose of this tutorial is to gain familiarity with MATLAB’s Image Processing Toolbox. This tutorial does not contain all of the functions available in MATLAB. It is very useful to go to HelpMATLAB Help in the MATLAB window if you have any questions not answered by this tutorial. Many of the examples in this tutorial are modified versions of MATLAB’s help examples. The help tool is especially useful in image processing applications, since there are numerous filter examples.

说明：  matlab工具箱在应用数学中的应用,包括统计/偏微分/样条/优化工具箱(matlab toolbox in the application of mathematics, including statistical/partial differential/spline/Optimization Toolbox)

本程序是基于WaveLab802平台作的。 包括 VisuShrink方法、SUREShrink方法、BayesShrink等方法。噪声方差大小和小波可以自行设定。(This procedure is based on the platform for WaveLab802. VisuShrink methods including, SUREShrink methods, BayesShrink and other methods. Size and wavelet noise variance can be set.)
