opencv python cool
当年做毕业论文的时候openCV就像是我的瑞士军刀，太有感情了。如今用了一年多的python，发现openCV也有python版本了，真是太酷了！当然python在处理图像时还可以用其它库例如PIL(Python Imaging Library )，一种轻量级的图像库。目前openCV1.0版本对应的python版本为2.5，openCV2.0对应python 2.6。

1. 一篇介绍图像处理库是 PIL(Python Image Library)的blog:

2. openCV简介
OpenCV全程open source computer vision library.是Intel开发的一个计算机视觉库，包含了多种计算机图形图像处理的库，目前版本为V1.0，可以在商业和研究领域免费实用。
主要用于处理
图像处理
计算机视觉
模式识别
物体识别(人脸识别，Object识别)
运动跟踪

安装python2.5
到以下地址下载, 然后默认安装.
http://www.python.org/ftp/python/2.5.2/python-2.5.2.msi
安装OpenCV
下载OpenCV, 安装后将对应的bin目录添加到PATH变量.
http://www.opencv.org.cn/download/OpenCV_1.0.exe
配置OpenCV的python接口
打开目录 OpenCV\interfaces\swig\python, 运行以下命令:
setup-for-win.py build
setup-for-win.py install
测试
编写以下代码:
# -*- coding:utf-8 -*-
# mycv.py
import sys
# 导入OpenCV模块
from opencv.cv import *
from opencv.highgui import *
if __name__ == '__main__':
# 打开图像
image = cvLoadImage ("lena.jpg")
# 创建窗口
cvNamedWindow ("mywin")
# 显示图像
cvShowImage ("mywin", image)
cvWaitKey (0)
