◆ 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.

◆ makePtr() [1/11]

template<typename T >
Ptr<T> cv::makePtr ( )

#include <opencv2/core/cvstd.hpp>

makePtr<T>(...) is equivalent to Ptr<T>(new T(...)). It is shorter than the latter, and it's marginally safer than using a constructor or Ptr::reset, since it ensures that the owned pointer is new and thus not owned by any other Ptr instance. Unfortunately, perfect forwarding is impossible to implement in C++03, and so makePtr is limited to constructors of T that have up to 10 arguments, none of which are non-const references.
