gpu::reduce

||||

|
||||
|
||||
:param mtx: Source 2D matrix.
|
||||
|
||||
:param vec: Destination vector. Its size and type is defined by ``dim`` and ``dtype`` parameters.
|
||||
|
||||
:param dim: Dimension index along which the matrix is reduced. 0 means that the matrix is reduced to a single row. 1 means that the matrix is reduced to a single column.
|
||||
|
||||
:param reduceOp: Reduction operation that could be one of the following:
|
||||
|
||||
* **CV_REDUCE_SUM** The output is the sum of all rows/columns of the matrix.
|
||||
|
||||
* **CV_REDUCE_AVG** The output is the mean vector of all rows/columns of the matrix.
|
||||
|
||||
* **CV_REDUCE_MAX** The output is the maximum (column/row-wise) of all rows/columns of the matrix.
|
||||
|
||||
* **CV_REDUCE_MIN** The output is the minimum (column/row-wise) of all rows/columns of the matrix.
|
||||
|
||||
:param dtype: 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())`` .
|
||||
|
||||
The function ``reduce`` reduces the 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. For example, the function can be used to compute horizontal and vertical projections of a 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.
