Squeeze out every little computation power from your system by using the power of your video card to run the OpenCV algorithms.
Similarity check (PNSR and SSIM) on the GPU
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.
Using a cv::cuda::GpuMat with thrust
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.
