computer vision contrlib library
This package contains the OpenCV (Open Computer Vision) opencv_contrib runtime libraries. This package contain following contrlib libraries: . - aruco - bgsegm - bioinspired - ccalib - dnn - dpm - fuzzy - hdf - line_descriptor - optflow - plot - reg - saliency - stereo - structured_light - rgbd - surface_matching - tracking - datasets - text - face - ximgproc - xobjdetect - xphoto . The Open Computer Vision Library is a collection of algorithms and sample code for various computer vision problems. The library is compatible with IPL (Intel's Image Processing Library) and, if available, can use IPP (Intel's Integrated Performance Primitives) for better performance. . OpenCV provides low level portable data types and operators, and a set of high level functionalities for video acquisition, image processing and analysis, structural analysis, motion analysis and object tracking, object recognition, camera calibration and 3D reconstruction.
