OpenLvVision_OpenCv.lvlib:Reduce.vim

Reduces a matrix to a vector.

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 REDUCE_MAX and REDUCE_MIN, the output image should have the same type as the source one. In case of REDUCE_SUM, REDUCE_SUM2 and REDUCE_AVG, the output may have a larger element bit-depth to preserve accuracy.

error in

error in can accept error information wired from VIs previously called. Use this information to decide if any functionality should be bypassed in the event of errors from other VIs.

Right-click the error in control on the front panel and select Explain Error or Explain Warning from the shortcut menu for more information about the error.

    cbool

    		status

    status is TRUE (X) if an error occurred or FALSE (checkmark) to indicate a warning or that no error occurred.

input 2D matrix.

cenum

ReduceType

REDUCE_SUM =the output is the sum of all rows/columns of the matrix.

REDUCE_AVG = the output is the mean vector of all rows/columns of the matrix.

REDUCE_MAX = the output is the maximum (column/row-wise) of all rows/columns of the matrix.

REDUCE_MIN = the output is the minimum (column/row-wise) of all rows/columns of the matrix.

REDUCE_SUM2 =the output is the sum of all squared rows/columns of the matrix.

cenum

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.
