GPU-Accelerated Computer Vision (cuda module)
Squeeze out every little computation power from your system by using the power of your video card to run the OpenCV algorithms.
Compatibility:> OpenCV 2.0
Author: Bernát Gábor
This will give a good grasp on how to approach coding on the GPU module, once you already know how to handle the other modules. As a test case it will port the similarity methods from the tutorial Video Input with OpenCV and similarity measurement to the GPU.
Compatibility:>= OpenCV 3.0
This tutorial will show you how to wrap a GpuMat into a thrust iterator in order to be able to use the functions in the thrust library.
