FUNCTIONgapi_add

RETURN TYPEGMat

Call structure. A void return can still write to destination arguments. The parameter descriptions define inputs, outputs and ownership.

namespace streaming

Calculates the per-element sum of two matrices.

The function add calculates sum of two matrices of the same size and the same number of channels:

\texttt{dst}(I) =  \texttt{saturate} ( \texttt{src1}(I) +  \texttt{src2}(I)) \quad \texttt{if mask}(I) \ne0

The function can be replaced with matrix expressions:

\texttt{dst} =  \texttt{src1} + \texttt{src2}

The input matrices and the output matrix can all have the same or different depths. For example, you can add a 16-bit unsigned matrix to a 8-bit signed matrix and store the sum as a 32-bit floating-point matrix. Depth of the output matrix is determined by the ddepth parameter. If src1.depth() == src2.depth(), ddepth can be set to the default -1. In this case, the output matrix will have the same depth as the input matrices.

Supported matrix data types are CV_8UC1, CV_8UC3, CV_16UC1, CV_16SC1, CV_32FC1.

Note: Function textual ID is "org.opencv.core.math.add"
