--- Comment #78 from caulier.gil...@gmail.com --- OpenCV provide a solution to disable 3D aceleration by API call: https://answers.opencv.org/question/123097/how-to-stop-using-gpu-in-opencv-32/?comment=123114 So typically, for each thread using OpenCV API, we need to call cv::ocl::setUseOpenCL(false) But it's problematic to use : https://github.com/opencv/opencv/issues/8035 In all case, we must not use cv::Umat which is optimized for OpenCV and use cv::Mat instead everywhere.
