Function merge4

Source 
pub fn merge4(
    src1: &impl GMatTraitConst,
    src2: &impl GMatTraitConst,
    src3: &impl GMatTraitConst,
    src4: &impl GMatTraitConst,
) -> Result<GMat>
Expand description

Creates one 4-channel matrix out of 4 single-channel ones.

The function merges several matrices to make a single multi-channel matrix. That is, each element of the output matrix will be a concatenation of the elements of the input matrices, where elements of i-th input matrix are treated as mv[i].channels()-element vectors. Output matrix must be of [CV_8UC4] type.

The function split4 does the reverse operation.

Note:

  • Function textual ID is “org.opencv.core.transform.merge4”

§Parameters

  • src1: first input [CV_8UC1] matrix to be merged.
  • src2: second input [CV_8UC1] matrix to be merged.
  • src3: third input [CV_8UC1] matrix to be merged.
  • src4: fourth input [CV_8UC1] matrix to be merged.
