直方图均衡化及亮度调整，关于图像处理方面最基本的几个程序(Histogram equalization and brightness adjustment, image processing on a few basic procedures)

指数平滑法是对时间序列进行预测常用的方法之一,其理论基础是趋势外延，即未来一定时期内事物在数量上的演变特征不脱离过去的发展趋势,预测值是以前所有观测值的加权和,且对不同的数据给予不同的权数,越近期数据给予越大的权数,越远期的数据给予越小的权数。(Exponential smoothing method is commonly used to predict the time series one of the ways, the theoretical basis of the trend of the extension, that is, a certain period of time what the next evolution in the number of characteristics are not out of the development trend of the past to predict the value of all previous observations is the weighted and, on different data and different weights given to more recent data to give greater weights, the more long-term data to give the smaller weights.)

对于随机数据和Iris数据的层次聚类算法(For random data and Iris data hierarchical clustering algorithm)

采用FIR最小二乘逆滤波器来实现反卷积 1.通过输入信号xn与传递函数gn求输出yn 2.通过使平方误差达到最小求出最佳延迟 3通过最佳延迟求得逆滤波器传递函数hn 4通过hn与yn进行卷积运算得到还原的输入信号xn1，进行对比 5按照题设要求，进行相关噪声添加，再次进行上述实验过程 (Using least squares FIR inverse filter to achieve deconvolution)

说明：  偏微分方程在图像处理中的应用代码,有图片及大量代码。(This program implement image interpolation by AMLE method. Firstly, get a number of level sets from an input image by thresholdding. The threshold values are chosen automatically. Then the boundaries for each level set are extracted, the image data on the boundaries are recorded. Finally, by using AMLE, extend those imformation to reconstract a new image, which will approximate the original one quitr well.)

利用MATLAB实现了二元光学设计中的GS算法以及达曼光栅的设计。GS算法是用于光束整形的重要算法，达曼光栅是常见的均匀分束二元光学器件。(Implemented using MATLAB binary optical design of the GS algorithm and Dammann grating design. GS algorithm is an important algorithm for beam shaping, Dammann grating is a common uniform beam of binary optics.)
