本实验开发一个通用程序， 用在后续的几个实验中。(a) 编写一个给图像中添加高斯噪声的程序，程序的输入参数为噪声的均值与方差。

(b) 编写一个给图像中添加椒盐噪声的程序，程序的输入参数为两个噪声分量的概率值。

-In this study, the development of a common procedure, used in the follow-up of several experiments. (A) preparing a program to add Gaussian noise to the image, the input parameters of the program is the noise mean and variance. (B) prepare a program to add salt and pepper noise in the image, the input parameters of the program is the probability that the value of the two noise components.
