Description: 练习读入lena.bmp图像，在workspace中查看图像，显示图像，并将此图像存储在C盘根目录下，命名为1.bmp。
读入两幅尺寸相同的图像(lena.bmp和sky.bmp)，做加法，实现双曝光的效果。
读入两幅尺寸相同的图像(2.bmp和2background.bmp)，做减法，实现减背景效果。
读入lena.bmp图像，编写一个模板，此模板是以图像中心为圆心，64像素为半径的圆内为1，其他位置为0，以此模板乘以读入的lena图像，显示结果。
用图像除法完成减背景操作（ 5.bmp和5background.bmp运用公式：f=g ÷ b х m ）。
已知信号整数时刻1至10秒的幅值为[10,25,33,17,50,5,76,17,78,80]，用线性插值方法，求[1.3,1.77,2.58,3.85,9.65]这5个时刻的信号幅值。（要自己写函数完成此题目，不要直接用matlab现成的插值函数）。
利用help文档，自学imrotate、imresize和imcrop函数的用法-Practice reading into lena.bmp images, view the image in the workspace, display images, and the images are stored in the root directory of C named 1.bmp.
Read into two of the same size the image (lena.bmp and sky.bmp) do addition, to achieve the effect of double exposure.
Read into the two dimensions same of images (2.bmp 2background.bmp), and subtract to achieve the effect of background subtraction.
The image reads lena.bmp write a template, this template is the center of the image to the center and 64 pixels for the radius of the circle is 1 other location, this template is multiplied by lena image reads and displays the results.
Image division completed less background operation (5.bmp, and 5background.bmp use of the formula: f = the g ÷ b х m).
The known signal integer time of 1-10 seconds amplitude [10,25,33,17,50,5,76,17,78,80 using a linear interpolation method,, [1.3,1.77,2.58,3.85, , 9.65] this is five times the signal amplitude. (To write your own functions to complete t

Description: 程序是对图像进行不同的处理，实验指导书放在根目录下，对lena图像进行转换、拉伸、锐化、求取误差，每一个处理相当于一个小程序，在MFC里设置了四个菜单来完成这些功能。raw格式图片只能在PS里查看，raw格式不懂可以问百度。一个很好的、系统的、完整的图像处理程序。很好的学习资料。-Program is for different image processing, the experiment instruction under the root directory, the Lena image transform, stretching, sharpen, calculate the error of each process is equivalent to a small program, set up four menu in the MFC to achieve these functions.Raw format images can only check in PS, raw format don t understand, can ask baidu.A good, system, complete the image processing program.Very good learning materials.

Description: Ural 1323 Classmates源码，递归、DFS-Description
Tanya almost left for school when the telephone rang. It was the director of studies. She said the first three lessons that day had been cancelled because of an electricity failure. Tanya was the head girl of the class and the director of studies asked her to pass this news to her classmates.
— What shall I do? — thought Tanya, — there is almost no time! OK, now I’m going to call Lena, then Katya, then Masha. Lena will meantime call Vitya, she knows his telephone number, Vitya will call Masha. No, I’ll call Masha myself: let him better call Misha. Katya will call Natasha... No, it won’t work. They quarreled yesterday. Thus there is no time to think. I must immediately call Lena. Hit-or-miss everyone will know the news.
Tanya managed to send this message to all her classmates. But someone knew it very late and someone heard this news several people. In the evening, Tanya decided to work out a plan of calls and not to let it ride the next time. After all, she is the head
