OpenCV教程（5）函数整理

本文就Python版OpenCV模块内全部函数进行抽调和汇总，便于深度理解OpenCV实现数字图像处理技术的原理。

Python：import cv2 as cv

在Mac终端上，输入以下指令导入OpenCV模块，并显示模块下的所有函数：

import cv2 as cv#take in a moduledir(cv)

内置函数dir()用于找出模块定义的名称。它返回一个排序的字符串列表：

关键词提取、分类

从终端shell获取的是一个排序的字符串列表，杂乱无章的名称和排序不便于查看分析，因此，需要对上述结果进行简单处理。

先新建一个txt文件，将上述结果写入，再用Python或C++对关键词进行提取并排序覆盖并写入文件。
shell创建文件：vim

userde-MacBook-Pro-5:Desktop ~$ cd Documents
userde-MacBook-Pro-5:Documents ~$ ls
userde-MacBook-Pro-5:Documents ~$ mkdir OpenCV_funtions # make a new direction
userde-MacBook-Pro-5:Documents ~$ cd OpenCV_funtions   #touch it######
# using vim create a new .txt document to save these names of opencv modual
# "i" is "insert"  ,and then "ESC"+shift+:+wq to close and save this file.
######userde-MacBook-Pro-5:OpenCV_funtions ~$ vim functions.txt

Python文件读写
