Make a function take a cv::Point2x

C++
6

you can define a temporary cv::Mat variable and add or subtract shifting values
take a look

#include <iostream>
#include <opencv2/core.hpp>

void TranslateSimpleContour(cv::Mat &contour, const int &shiftHorizontal, const int &shiftVertical) // translate simple contour along vertical and/or horizontal axis
{
    cv::Scalar t(shiftHorizontal, shiftVertical);
    contour = contour + t;
}

template <typename PointType>
void TranslateSimpleContour(std::vector<PointType>& contour, typename PointType::value_type shiftHorizontal, typename PointType::value_type shiftVertical)
{
    PointType translation(shiftHorizontal, shiftVertical);
    for (auto& point : contour)
    {
        point += translation;
    }
}
