2016-02-15 14:19:54 -0600 | asked a question | cuda::Stream in v3 (CudaMem, Stream::enqueUpload()) I am trying to rewrite some CPU algorithm in OpenCV-3.1 Cuda with streams. I've figured out that API changed. I've looked at the docs, samples directory and I've googled for it. No answer. It seams that type CudaMem was changed to HostMem. When I am trying to use stream upload, I am getting: How to use streams with page locked memory in OpenCV-3.1? |

2016-02-01 06:30:35 -0600 | asked a question | Querying and controlling OpenCV on used accelaration method I was doing testing of OpenCV background subtraction algorithms. After recompiling OpenCV (from github, tagged as 3.1) and adding CUDA and EIGEN, I've noticed that MOG2 became about 30% faster but KNN became 4 times slower. I also have OPENCL, IPP, TBB and SSE/AVX enabled. I usually use one universal include file (opencv2/opencv.hpp) Is there a way to find out what acceleration method OpenCV have used in its functions? Or is there a way to control what acceleration method will be used? |
