Description:

The OpenCV GPU module is a set of classes and functions to utilize GPU
computational capabilities. It is implemented using NVIDIA* CUDA* Runtime
API and supports only NVIDIA GPUs. The OpenCV GPU module includes utility
functions, low-level vision primitives, and high-level algorithms. The
utility functions and low-level primitives provide a powerful infrastructure
for developing fast vision algorithms taking advantage of GPU whereas
the high-level functionality includes some state-of-the-art algorithms
(such as stereo correspondence, face and people detectors, and others)
ready to be used by the application developers.
