import { gapi_mul } from '@banou/opencv-wasm'

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

ARGUMENTSsrc1, src2, scale, ddepth
FUNCTIONgapi_mul
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 scaled product of two matrices.

The function mul calculates the per-element product of two matrices:

\texttt{dst} (I)= \texttt{saturate} ( \texttt{scale} \cdot \texttt{src1} (I)  \cdot \texttt{src2} (I))

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. The matrices can be single or multi channel. Output matrix must have the same size 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.math.mul"

src1

first input matrix.

src2
