static member Reduce : 
        src : InputArray * 
        dst : OutputArray * 
        dim : ReduceDimension * 
        rtype : ReduceOperation * 
        dtype : int -> unit 

Parameters

src

Type: OpenCvSharp.CPlusPlusInputArray
The source 2D matrix

dst

Type: OpenCvSharp.CPlusPlusOutputArray
The destination vector. Its size and type is defined by dim and dtype parameters

dim

Type: OpenCvSharpReduceDimension
The dimension index along which the matrix is reduced. 0 means that the matrix is reduced to a single row and 1 means that the matrix is reduced to a single column

rtype

Type: OpenCvSharpReduceOperation

[Missing <param name="rtype"/> documentation for "M:OpenCvSharp.CPlusPlus.Cv2.Reduce(OpenCvSharp.CPlusPlus.InputArray,OpenCvSharp.CPlusPlus.OutputArray,OpenCvSharp.ReduceDimension,OpenCvSharp.ReduceOperation,System.Int32)"]

dtype

Type: SystemInt32
When it is negative, the destination vector will have the same type as the source matrix, otherwise, its type will be CV_MAKE_TYPE(CV_MAT_DEPTH(dtype), mtx.channels())
