enum cv::cuda::FeatureSet |
#include <opencv2/core/cuda.hpp>
Enumeration providing CUDA computing features.
void cv::cuda::convertFp16 | ( | InputArray | _src, |
OutputArray | _dst, | ||
Stream & | stream = Stream::Null() |
||
) |
#include <opencv2/core/cuda.hpp>
Converts an array to half precision floating number.
_src | input array. |
_dst | output array. |
stream | Stream for the asynchronous version. |
bool cv::cuda::deviceSupports | ( | FeatureSet | feature_set | ) |
#include <opencv2/core/cuda.hpp>
checks whether current device supports the given feature
int cv::cuda::getCudaEnabledDeviceCount | ( | ) |
#include <opencv2/core/cuda.hpp>
Returns the number of installed CUDA-enabled devices.
Use this function before any other CUDA functions calls. If OpenCV is compiled without CUDA support, this function returns 0. If the CUDA driver is not installed, or is incompatible, this function returns -1.
int cv::cuda::getDevice | ( | ) |
#include <opencv2/core/cuda.hpp>
Returns the current device index set by cuda::setDevice or initialized by default.
void cv::cuda::printCudaDeviceInfo | ( | int | device | ) |
#include <opencv2/core/cuda.hpp>
void cv::cuda::printShortCudaDeviceInfo | ( | int | device | ) |
#include <opencv2/core/cuda.hpp>
void cv::cuda::resetDevice | ( | ) |
#include <opencv2/core/cuda.hpp>
Explicitly destroys and cleans up all resources associated with the current device in the current process.
Any subsequent API call to this device will reinitialize the device.
void cv::cuda::setDevice | ( | int | device | ) |
#include <opencv2/core/cuda.hpp>
Sets a device and initializes it for the current thread.
device | System index of a CUDA device starting with 0. |
If the call of this function is omitted, a default device is initialized at the fist CUDA usage.
