OpenCV (Open Source Computer Vision Library: ) is an open-source BSD-licensed library that includes several hundreds of computer vision algorithms. The document describes the so-called OpenCV API, which is essentially a C++ API, as opposite to the C-based OpenCV API. The latter is described in . OpenCV has a modular structure, which means that the package includes several shared or static libraries. The following modules are available: • core - a compact module defining basic data structures, including the dense multi-dimensional array Mat and basic functions used by all other modules. • imgproc - an image processing module that includes linear and non-linear image filtering,. | The OpenCV Reference Manual Release July 01 2013 CONTENTS 1 Introduction 1 API Concepts. 1 2 core.
