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.
我找到了这个参考,但似乎它不适用于我的情况.你有什么指示我怎么能用 OpenCV C++ 接口做到这一点?
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?
OpenCV 2.4:
OpenCV 2.4:
src.copyTo(dst(Rect(left, top, src.cols, src.rows)));
OpenCV 2.x:
OpenCV 2.x:
Mat dst_roi = dst(Rect(left, top, src.cols, src.rows));
src.copyTo(dst_roi);
这篇关于在另一个 ROI 内复制一个 cv::Mat的文章就介绍到这了,希望我们推荐的答案对大家有所帮助,也希望大家多多支持html5模板网!
