Use after await initOpenCV(). See the initialization and named imports guide.

ARGUMENTSsrc1, src2
FUNCTIONgapi_absDiff
RETURN TYPEGMat
Call structure. A void return can still write to destination arguments. The parameter descriptions define inputs, outputs and ownership.

Calculates the per-element absolute difference between two matrices.

The function absDiff calculates absolute difference between two matrices of the same size and depth:

\texttt{dst}(I) =  \texttt{saturate} (| \texttt{src1}(I) -  \texttt{src2}(I)|)

where I is a multi-dimensional index of matrix elements. In case of
multi-channel matrices, each channel is processed independently.

Output matrix must have the same size and depth as 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.matrixop.absdiff"

See: abs

gapi_absDiff(src1: GMat, src2: GMat): GMat;
src1

first input matrix.

src2

second input matrix.

Returns

The GMat result. Release returned native handles with using or delete(), including handles nested in results.
