说明：  使用c++语言处理图像，可以对图像进行Perona-Malik的模仿。 Cpp1.cpp包含了所有代码 分为读取图像函数，高斯平滑，基于Perona-Malik模型的离散化处理，使图像得到平滑，一致噪声，里面还包括了保存处理过后的图像函数。
(Use c++ Language processing images, can images mimic the Perona-Malik. Cpp1.cpp contains all the code to read images is divided into function, Gaussian smoothing, Perona-Malik model based on the discretization of treatment, so that the image has been smooth, coherent noise, which also includes the preservation of the image function after treatment.)
