我需要将 cv::Mat 图像(源)复制到另一个(目标)cv::Mat 图像的 ROI.

I need to copy a cv::Mat image (source) to an ROI of another (Destination) cv::Mat image.

我找到这个参考，但似乎它不适用于我的情况.你有什么指示我如何使用 OpenCV C++ 接口来做到这一点?

I found this reference, but it seems that it does not work for my case. Do you have any pointers how could I do this using the OpenCV C++ interface?
