Description: 差影法实际是对图像进行代数运算的一种不同的叫法。代数运算是指对两幅输入图像进行点对点的加、减、乘、除计算而得到输出图像的运算。
图像相加的一个重要应用就是对同一场景的多幅图像求平均值，它可以有效地降低随机噪声的影响，这是因为对于一幅有噪声的图像S（x，y），可以看成是由原始无噪声的图像F（x，y）和噪声G（x，y）叠加而成的，即
S（x，y）=G（x，y）+F（x，y）
-Poor shadow method is actually an image algebra in a different name for. Algebra refers to the two input images point to point add, subtract, multiply, in addition to the calculation obtained computing the output image. An important application of the image is the sum of the same scene multiple images averaged, it can effectively reduce the impact of random noise, it is because for a noisy image S (x, y), can be seen as by the original noise-free images F (x, y) and noise G (x, y) stacking, that is, S (x, y) = G (x, y)+ F (x, y)

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
