Function opencv::core::hconcat

pub fn hconcat(
    src: &impl ToInputArray,
    dst: &mut impl 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.
