%description
    OpenCV (Open Source Computer Vision Library) is an open source
    computer vision and machine learning software library. OpenCV
    was built to provide a common infrastructure for computer vision
    applications and to accelerate the use of machine perception in the
    commercial products. OpenCV makes it easy for businesses to utilize
    and modify the code. The library has more than 2500 optimized
    algorithms, which includes a comprehensive set of both classic and
    state-of-the-art computer vision and machine learning algorithms.
    These algorithms can be used to detect and recognize faces, identify
    objects, classify human actions in videos, track camera movements,
    track moving objects, extract 3D models of objects, produce 3D point
    clouds from stereo cameras, stitch images together to produce a
    high resolution image of an entire scene, find similar images from
    an image database, remove red eyes from images taken using flash,
    follow eye movements, recognize scenery and establish markers to
    overlay it with augmented reality, etc.
