Function opencv::core::hconcat2

pub fn hconcat2(
    src1: &dyn ToInputArray, 
    src2: &dyn ToInputArray, 
    dst: &mut dyn ToOutputArray
) -> Result<()>

Applies horizontal concatenation to given matrices.

The function horizontally concatenates two or more cv::Mat matrices (with the same number of rows).

   cv::Mat matArray[] = { cv::Mat(4, 1, CV_8UC1, cv::Scalar(1)),
                           cv::Mat(4, 1, CV_8UC1, cv::Scalar(2)),
                           cv::Mat(4, 1, CV_8UC1, cv::Scalar(3)),};
 
   cv::Mat out;
   cv::hconcat( matArray, 3, out );
   //out:
   //[1, 2, 3;
   // 1, 2, 3;
   // 1, 2, 3;
   // 1, 2, 3]

Parameters

• src: input array or vector of matrices. all of the matrices must have the same number of rows and the same depth.
• nsrc: number of matrices in src.
• dst: output array. It has the same number of rows and depth as the src, and the sum of cols of the src.

  cv::Mat C;
  cv::hconcat(A, B, C);
  //C:
  //[1, 4, 7, 10;
  // 2, 5, 8, 11;
  // 3, 6, 9, 12]

• src1: first input array to be considered for horizontal concatenation.
• src2: second input array to be considered for horizontal concatenation.
• dst: output array. It has the same number of rows and depth as the src1 and src2, and the sum of cols of the src1 and src2.
