1、OpenCV 的下载地址:http://sourceforge.net/projects/opencvlibrary/
2、有用的网址:
(1) Visit OpenCV Wiki-pages at http://opencv.willowgarage.com/wiki/ and look for the information there (and/or add it when you have found a solution)
(2) Search through OpenCV archives at www.yahoogroups.com (http://groups.yahoo.com/group/OpenCV/)

(4) Look at the OpenCV sample code, read the reference manual ( http://opencv.willowgarage.com/documentation/index.html )
(5) OpenCV 中文
