amynka@gentoo.org Amy Liffey OpenCV (Open Source Computer Vision) is a library of programming functions mainly aimed at real time computer vision. Example applications of the OpenCV library are Human-Computer Interaction (HCI); Object Identification, Segmentation and Recognition; Face Recognition; Gesture Recognition; Motion Tracking, Ego Motion, Motion Understanding; Structure From Motion (SFM); and Mobile Robotics.
