[VC/MFC] 10image DL : 0: 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)
