penCV is an open source computer vision and
machine learning library for C/C++/Python
available for Windows, Linux, macOS, and
Android platforms. It contains low-level image
processing functions as well as high-level
algorithms such as object identification, face recognition,
and action classification in videos. OpenCV has become
very popular, with more than 47,000 people in its user
community and 18 million downloads (see https://opencv
.org/about/). Under a Berkeley Software Distribution
(BSD) license, it can be used for both academic and commercial applications.

A significant part of computer vision is image processing, with massive parallel computations. Modern graphics
processing units (GPUs) are highly parallel, multicore systems, powerful enough to perform general purpose computations on large blocks of data. So it is challenging, yet
potentially very rewarding, to accelerate OpenCV on
graphics processors.
Background
CUDA is a parallel computing architecture created by Nvidia
that makes it possible to use the many computing cores in a
GPU to perform general-purpose mathematical calculations
[1]. However, it only works on Nvidia cards.
OpenCV and CUDA have been available for more than 10
years [2], and their use has increased significantly; however,
