Enumerator
DEFAULT 

Default event flag

BLOCKING_SYNC 

Event uses blocking synchronization

DISABLE_TIMING 

Event will not record timing data

INTERPROCESS 

Event is suitable for interprocess use. DisableTiming must be set

Constructor & Destructor Documentation

cv::cuda::Event::Event ( Event::CreateFlags  flags = Event::CreateFlags::DEFAULT)
explicit
Python:
