GpuMat Class

http://www.emgu.com

A GpuMat, use the generic version if possible. The non generic version is good for use as buffer in stream calls.

The GpuMat type exposes the following members.

Constructors

	Name	Description
	GpuMat	Create an empty GpuMat
	GpuMat(IInputArray)	Create a GpuMat from an CvArray of the same depth type
	GpuMat(GpuMat, Range, Range)	Create a GpuMat from the specific region of mat. The data is shared between the two GpuMat
	GpuMat(Int32, Int32, DepthType, Int32, Boolean)	Create a GpuMat of the specified size

Properties

	Name	Description
	Bitmap	Get the Bitmap from this GpuMat
	Depth	Depth type
	IsContinuous	True if the data is continues
	IsEmpty	True if the matrix is empty
	NumberOfChannels	Number of channels
	Ptr	Pointer to the unmanaged object (Inherited from UnmanagedObject.)
	Size	Get the GpuMat size: width == number of columns, height == number of rows
	Type	Get the type of the GpuMat

Methods

	Name	Description
	Clone	Make a clone of the GpuMat
	Col	Returns a GpuMat corresponding to the ith column of the GpuMat. The data is shared with the current GpuMat.
	ColRange	Returns a GpuMat corresponding to the [startend) columns of the GpuMat. The data is shared with the current GpuMat.
	ConvertTo	This function has several different purposes and thus has several synonyms. It copies one GpuMat to another with optional scaling, which is performed first, and/or optional type conversion, performed after: dst(I)=src(I)*scale + (shift,shift,...) All the channels of multi-channel GpuMats are processed independently. The type conversion is done with rounding and saturation, that is if a result of scaling + conversion can not be represented exactly by a value of destination GpuMat element type, it is set to the nearest representable value on the real axis. In case of scale=1, shift=0 no prescaling is done. This is a specially optimized case and it has the appropriate convertTo synonym.
	CopyTo	Copy the source GpuMat to destination GpuMat, using an optional mask.
	Create	allocates new GpuMat data unless the GpuMat already has specified size and type
	Dispose	The dispose function that implements IDisposable interface (Inherited from DisposableObject.)
	DisposeObject	Release the unmanaged memory associated with this GpuMat (Overrides DisposableObjectDisposeObject.)
	Download	Downloads data from device to host memory.
	Equals(Object)	(Inherited from Object.)
	Equals(GpuMat)	Returns true if the two GpuMat equals
	Finalize	Destructor (Inherited from DisposableObject.)
	GetData	Get a copy of the data values as an array
	GetHashCode	(Inherited from Object.)
	GetInputArray	Pointer to the InputArray
	GetInputOutputArray	Pointer to the InputOutputArray
	GetOutputArray	Pointer to the OutputArray
	GetType	(Inherited from Object.)
	MemberwiseClone	(Inherited from Object.)
	MergeFrom	Makes multi-channel array out of several single-channel arrays
	MinMax	Returns the min / max location and values for the image
	ReleaseManagedResources	Release the managed resources. This function will be called during the disposal of the current object. override ride this function if you need to call the Dispose() function on any managed IDisposable object created by the current object (Inherited from DisposableObject.)
	Reshape	Changes shape of GpuMat without copying data.
	Row	Returns a GpuMat corresponding to the ith row of the GpuMat. The data is shared with the current GpuMat.
	RowRange	Returns a GpuMat corresponding to the [startend) rows of the GpuMat. The data is shared with the current GpuMat.
	Save	Save the GpuMat to a file
	SetTo	Copies scalar value to every selected element of the destination GpuMat: arr(I)=value if mask(I)!=0
	Split	Split current GpuMat into an array of single channel GpuMat where each element in the array represent a single channel of the original GpuMat
	ToMat	Convert the GpuMat to Mat
	ToString	(Inherited from Object.)
	Upload	Upload data to GpuMat

Fields

	Name	Description
	_ptr	A pointer to the unmanaged object (Inherited from UnmanagedObject.)

Extension Methods

	Name	Description
	ForEachDuplicateChannel(ActionIInputArray, Int32)	Overloaded. Apply converter and compute result for each channel of the image, for single channel image, apply converter directly, for multiple channel image, make a copy of each channel to a temperary image and apply the convertor (Defined by IInputArrayExtensions.)
	ForEachDuplicateChannelTReturn(FuncIInputArray, Int32, TReturn)	Overloaded. Apply converter and compute result for each channel of the image, for single channel image, apply converter directly, for multiple channel image, make a copy of each channel to a temperary image and apply the convertor (Defined by IInputArrayExtensions.)
	IsUmat	Determines whether the specified input array is umat. (Defined by IInputArrayExtensions.)
