Public Methods

Method	Description
EnqueueConvert ( GpuMat src, GpuMat dst, int dtype, double a = 1, double b ) : void	converts matrix type, ex from float to uchar depending on type
EnqueueCopy ( GpuMat src, GpuMat dst ) : void	Copy asynchronously
EnqueueDownload ( GpuMat src, Mat dst ) : void	Downloads asynchronously. Warning! cv::Mat must point to page locked memory (i.e. to CudaMem data or to its subMat)
EnqueueHostCallback ( StreamCallback callback, object userData = null ) : void	Adds a callback to be called on the host after all currently enqueued items in the stream have completed
EnqueueMemSet ( GpuMat src, Scalar val ) : void	Memory set asynchronously
EnqueueMemSet ( GpuMat src, Scalar val, GpuMat mask ) : void	Memory set asynchronously
EnqueueUpload ( Mat src, GpuMat dst ) : void	Uploads asynchronously. Warning! cv::Mat must point to page locked memory (i.e. to CudaMem data or to its ROI)
QueryIfComplete ( ) : bool
Release ( ) : void	Clean up any resources being used.
Stream ( ) : System	Creates empty Stream
Stream ( IntPtr ptr ) : System	Creates from native cv::gpu::Stream* pointer
Stream ( Stream m ) : System
WaitForCompletion ( ) : void

Method	Description
Dispose ( bool disposing ) : void	Clean up any resources being used.

Clean up any resources being used.

protected Dispose ( bool disposing ) : void
disposing	bool	/// If disposing equals true, the method has been called directly or indirectly by a user's code. Managed and unmanaged resources can be disposed. /// If false, the method has been called by the runtime from inside the finalizer and you should not reference other objects. Only unmanaged resources can be disposed. ///
