Reduce(InputArray, OutputArray, ReduceDimension, ReduceTypes, int)

transforms 2D matrix to 1D row or column vector by taking sum, minimum, maximum or mean value over all the rows

public static void Reduce(InputArray src, OutputArray dst, ReduceDimension dim, ReduceTypes rtype, int dtype)

Parameters

src InputArray

The source 2D matrix

dst OutputArray

The destination vector. Its size and type is defined by dim and dtype parameters

dim ReduceDimension

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 ReduceTypes

dtype int

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())
