Function opencv::core::merge

pub fn merge(mv: &dyn ToInputArray, dst: &mut dyn ToOutputArray) -> Result<()>

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. @snippet snippets/core_merge.cpp example

Parameters

• mv: input array of matrices to be merged; all the matrices in mv must have the same size and the same depth.
• count: number of input matrices when mv is a plain C array; it must be greater than zero.
• dst: output array of the same size and the same depth as mv[0]; The number of channels will be equal to the parameter count.

Overloaded parameters

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