◆ UMatUsageFlags

enum cv::UMatUsageFlags

#include <opencv2/core/mat.hpp>

Usage flags for allocator.

Warning: All flags except USAGE_DEFAULT are experimental.; For the OpenCL allocator, USAGE_ALLOCATE_SHARED_MEMORY depends on OpenCV's optional, experimental integration with OpenCL SVM. To enable this integration, build OpenCV using the WITH_OPENCL_SVM=ON CMake option and, at runtime, call cv::ocl::Context::getDefault().setUseSVM(true); or similar code. Note that SVM is incompatible with OpenCL 1.x.
