本文详细介绍了OpenCV在Python中的API使用，基于《The OpenCV Reference Manual, Release 2.4.8.0》的资料，涵盖了C++、C及Python三种接口的对比，特别强调了Python开头的599行API，帮助开发者更好地理解和应用OpenCV的Python接口。" 88808139,8457732,Python线程同步：Lock、Condition、Queue与Event,"['Python', '多线程', '线程同步']

学习Python和OpenCV, 用gAWK抽出OpenCV函数方便查找，

从《The OpenCV Reference Manual, Release 2.4.8.0 》输出：章节行，函数行，页码

C++开头 1632行

C开头 469 行

Python开头 599行

以下是Python API，文字自动生成，很是粗糙，记录一下，看自己能走多远。2014.03.19
