"""
OpenCV is released under a BSD license and hence it's free for both academic and commercial use. It has C++, C,
Python and Java interfaces and supports Windows, Linux, Mac OS, iOS and Android. OpenCV was designed for
computational efficiency and with a strong focus on real-time applications. Written in optimized C/C++, the library
can take advantage of multi-core processing. Enabled with OpenCL, it can take advantage of the hardware
acceleration of the underlying heterogeneous compute platform. Adopted all around the world, OpenCV has more than
47 thousand people of user community and estimated number of downloads exceeding 9 million. Usage ranges from
interactive art, to mines inspection, stitching maps on the web or through advanced robotics.
