CvArrayTDepthReduceTOtherDepth Method

http://www.emgu.com

Reduces matrix to a vector by treating the matrix rows/columns as a set of 1D vectors and performing the specified operation on the vectors until a single row/column is obtained.

Namespace: Emgu.CV
Assembly: Emgu.CV.World (in Emgu.CV.World.dll) Version: 4.1.1.3497 (4.1.1.3497)

Syntax

C++

Copy

public void Reduce<TOtherDepth>(
	CvArray<TOtherDepth> array1D,
	ReduceDimension dim,
	ReduceType type
)
where TOtherDepth : new()

Public Sub Reduce(Of TOtherDepth As New) ( 
	array1D As CvArray(Of TOtherDepth),
	dim As ReduceDimension,
	type As ReduceType
)

public:
generic<typename TOtherDepth>
where TOtherDepth : gcnew()
void Reduce(
	CvArray<TOtherDepth>^ array1D, 
	ReduceDimension dim, 
	ReduceType type
)

member Reduce : 
        array1D : CvArray<'TOtherDepth> * 
        dim : ReduceDimension * 
        type : ReduceType -> unit  when 'TOtherDepth : new()

Parameters

array1D: Type: Emgu.CVCvArrayTOtherDepth
The destination single-row/single-column vector that accumulates somehow all the matrix rows/columns
dim: Type: Emgu.CV.CvEnumReduceDimension
The dimension index along which the matrix is reduce.
type: Type: Emgu.CV.CvEnumReduceType
The reduction operation type

Type Parameters

TOtherDepth: The type of depth of the reduced array

Remarks

The function can be used to compute horizontal and vertical projections of an raster image. In case of CV_REDUCE_SUM and CV_REDUCE_AVG the output may have a larger element bit-depth to preserve accuracy. And multi-channel arrays are also supported in these two reduction modes
