Classes
class	cv::cann::AscendMat::Allocator
class	cv::cann::AscendEvent
	AscendEvent to synchronize between different streams. More...
class	cv::cann::AscendMat
class	cv::cann::AscendStream
	In AscendCL Stream(AscendStream) is a task queue. Stream is used to manage the parallelism of tasks. The tasks inside a Stream are executed sequentially, that is, the Stream executes sequentially according to the sent tasks; the tasks in different Streams are executed in parallel. More...
