Functions | |
CV_EXPORTS int | getCudaEnabledDeviceCount () |
Returns the number of installed CUDA-enabled devices. | |
CV_EXPORTS void | setDevice (int device) |
Sets a device and initializes it for the current thread. | |
CV_EXPORTS int | getDevice () |
Returns the current device index set by cuda::setDevice or initialized by default. | |
CV_EXPORTS void | resetDevice () |
Explicitly destroys and cleans up all resources associated with the current device in the current process. | |
CV_EXPORTS bool | deviceSupports (FeatureSet feature_set) |
checks whether current device supports the given feature |

Function Documentation
CV_EXPORTS bool cv::cuda::deviceSupports | ( | FeatureSet | feature_set ) |
checks whether current device supports the given feature
CV_EXPORTS 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.
CV_EXPORTS int cv::cuda::getDevice | ( | ) |
Returns the current device index set by cuda::setDevice or initialized by default.
CV_EXPORTS 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.
CV_EXPORTS 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.
