Detailed Description

Enumeration Type Documentation

Enumeration providing CUDA computing features.

bool cv::cuda::deviceSupports ( FeatureSet feature_set )

checks whether current device supports the given feature

int cv::cuda::getCudaEnabledDeviceCount ( )

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.

int cv::cuda::getDevice ( )

Returns the current device index set by cuda::setDevice or initialized by default.

void cv::cuda::printCudaDeviceInfo ( int device )

void cv::cuda::printShortCudaDeviceInfo ( int device )

void cv::cuda::resetDevice ( )

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 )

Sets a device and initializes it for the current thread.

Parameters

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.
