Enumeration Type Documentation

enum FeatureSet

Enumeration providing CUDA computing features.

Function Documentation

bool deviceSupports ( FeatureSet feature_set )

checks whether current device supports the given feature

Definition at line 98 of file cuda_info.cpp.

int 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.

Definition at line 48 of file cuda_info.cpp.

int getDevice ( )

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

Definition at line 77 of file cuda_info.cpp.

void 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.

Definition at line 89 of file cuda_info.cpp.

void 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.
