我正在将旧的测试应用程序从 OpenCV C 接口迁移到新的 C++ 接口(我希望学习它).使用 C++ 接口时,cvSetImageROI
和 cvResetImageROI
的等价物是什么?我在文档中找不到它.
I'm migrating an old test application from the OpenCV C interface to the new C++ interface (I wish to learn it). What's the equivalent, using the C++ interface, of cvSetImageROI
and cvResetImageROI
? I couldn't find it in the documentation.
其实就在 文档.为我感到羞耻.
Actually, it's right on the docs. Shame on me.
//Make a rectangle
Rect roi(10, 20, 100, 50);
//Point a cv::Mat header at it (no allocation is done)
Mat image_roi = image(roi)
这篇关于相当于OpenCV C++接口中的cvSetImageROI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跟版网!
