OpenCV 2.3.1 Python Bindings installation on Windows 7

Today I searched several post about how to install OpenCV Python bindings on Windows 7. And I found many of them made it too complicated.

Here is my simple solution. Many thanks to Christoph Gohlke, Laboratory for Fluorescence Dynamics, University of California, Irvine, his work makes many Python modules be easy to be installed on Windows.

Simple steps:

  1. Install numpy for python, as OpenCV 2.3.1 needs this. normally choose the MKL version and the relevant python version and OS architecture( x86 or amd64)
  2. Install OpenCV , choose the relevant python version and OS architecture( x86 or amd64) as numpy
  3. The tricky part: as opencv 2.3.1 has been evolved to cv2, the old cv functions has been moved to cv2.cv. The workaround is create a cv.py file with
    from cv2.cv import *
    
  4. Copy this cv.py file under directory %PYTHON_HOME%\Lib\site-packages
  5. Now you can import cv to wrote OpenCV code. Have fun:)

Windows CMD命令之强大的for命令

因为工作需要,需要把一个目录下每个子文件夹里面的所有的MIDlet文件提取到其根目录下,就是目录遍历的问题。之前都是手动机械的重复劳动,就觉着机械劳动肯定可以用代码解决。for命令最适合干这个了。一直觉得Windows的命令应该就能搞定,但是里面的for命令以前接触过,没怎么用过,觉得很复杂。

今天上班又要这样重复劳动,就打算正式开始着手写个解决方案。下面包括了自己的思维走向:
