中文说明：第一个代码：图像处理中有时候处理的图片很多，但是一般的程序是一句只能处理几个或者一个图片，但是当你的文件夹有成千上百的图片，就不能这样处理了。我在网上找了找，但是好多都不对，或者又太麻烦，不知道写的是什么。好气人，然后自己试着写了写，成功了，简单易懂，希望大家支持，今后还会发出很多好的代码
English Description：
The first code: image processing sometimes deal with a lot of pictures, but general program is a sentence can only deal with a few or a picture, but when the folder that you have hundreds of thousands of images, it is not such treatment. I found on the Internet, but a lot of it is not right, or too much trouble, do not know what to write. Irritating, and then try to write to write, successful, easy to understand, hope everybody to support, in the future will be a lot of good code
