Intel Open Source Computer Vision Library
Intelの作ってるコンピュータビジョン用のライブラリ
IPL (Intel Image Processing Library)をベースにコーディングされ、パターン認識(顔認識)や輪郭抽出とかの処理が揃ってる。

- OpenCV 2.0からはC++ Interfaceに対応し、「cv」という名前空間が登場
- OpenCV 2.0から新たに，モダンな C++ インタフェースが導入されました． これは，短くて明瞭（短いコードで同じことができる），かつ型安全（ CvArr* ，いわゆる void* が不要に）で， OpenCV をより便利に使えるようになっています

OpenCV 2.2以降
The library has been reorganized. Instead of cxcore, cv, cvaux, highgui and ml we now have several smaller modules:
- opencv_core? - core functionality (basic structures, arithmetics and linear algebra, dft, XML and YAML I/O ...).
- opencv_imgproc? - image processing (filter, GaussianBlur?, erode, dilate, resize, remap, cvtColor, calcHist etc.)
- opencv_highgui? - GUI and image & video I/O
- opencv_ml? - statistical machine learning models (SVM, Decision Trees, Boosting etc.)
- opencv_features2d? - 2D feature detectors and descriptors (SURF, FAST etc.,including the new feature detectors-descriptor-matcher framework)
- opencv_video? - motion analysis and object tracking (optical flow, motion templates, background subtraction)
- opencv_objdetect? - object detection in images (Haar & LBP face detectors, HOG people detector etc.)
- opencv_calib3d? - camera calibration, stereo correspondence and elements of 3D data processing
- opencv_flann? - the Fast Library for Approximate Nearest Neighbors (FLANN 1.5) and the OpenCV wrappers
- opencv_contrib - contributed code that is not mature enough
- opencv_legacy? - obsolete code, preserved for backward compatibility
- opencv_gpu? - acceleration of some OpenCV functionality using CUDA (relatively unstable, yet very actively developed part of OpenCV)
