imageprocessing2
1.灰度变换：选择一幅对比度不足的图像，对该图像进行灰度变换,增强对比度，显示增强前、后的图像以及它们的灰度直方图。
2.直方图均衡：选择一幅灰度直方图不均匀的图像，对该图像进行直方图均衡处理，显示处理前、后的图像以及它们的灰度直方图。
3.选择一幅边缘较模糊的图像，利用高通滤波器（选择或自己设计）对该图像进行边缘增强，观察增强的效果。
4.选择一幅图像，叠加零均值高斯噪声，分别利用低通滤波器、维纳滤波器和中值滤波器对该有噪图像进行滤波，显示滤波后的图
像，比较各滤波器的滤波效果。
5.选择一幅图像，叠加椒盐噪声，分别利用低通滤波器、中值滤波器对该有噪图像进行滤波，显示滤波后的图像，比较各滤波器的

Experimental nature: comprehensiveness and research exploration
The purpose of the experiment is to skillfully use the portfolio toolbox, learn to construct effective frontier portfolio method, grasp the best investment portfolio calculation method, and give the value of portfolio VaR.
Experimental tasks: select stock and download data from Wan De, calculate the expected return, standard deviation and covariance of securities, set up a set of constraints, construct the optimal portfolio and calculate the Var value of the portfolio.
Experimental equipment: computer
Experimental software: Matlab2013 Wind database
A group of stocks is selected as investment target, and a portfolio is constructed. By estimating the mean value, variance and covariance of the yield, we calculate the portfolio weight, value at risk and draw effective frontier.)
