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

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

Creates one multi-channel array out of several single-channel ones.

The function cv::merge merges several arrays to make a single multi-channel array. That is, each element of the output array will be a concatenation of the elements of the input arrays, where elements of i-th input array are treated as mv[i].channels()-element vectors.

The function cv::split does the reverse operation. If you need to shuffle channels in some other advanced way, use cv::mixChannels.

The following example shows how to merge 3 single channel matrices into a single 3-channel matrix.

See: mixChannels, split, Mat::reshape

merge(mv: MatVector, dst: Mat): void;
mv

input vector of matrices to be merged; all the matrices in mv must have the same size and the same depth.

dst

Output destination, filled by the native operation. output array of the same size and the same depth as mv[0]; The number of channels will be the total number of channels in the matrix array.
