说明：  OpenCV是Intel公司支持的开源计算机视觉库。它轻量级而且高效——由一系列 C 函数和少量 C++ 类构成，实现了图像处理和计算机视觉方面的很多通用算法。 这本书是一本OPENCV入门书
(OpenCV is supported by Intel s Open Source Computer Vision Library. It is lightweight and highly efficient- by a series of C functions and a small amount of C++ classes that implement the image processing and computer vision in a lot of common algorithms. This book is a primer OPENCV)
