Just a general question. Instead of having a popup window appear when I use imshow, is it possible to have this window open up in a GUI application (could be any GUI framework, I am just wondering if this is possible) view instead?
It is possible to design a Window-based application using highgui, the same api that you use for displaying pop-up windows. But I am not sure how powerful it is, when it comes to designing a fully fledged application.
If you are using python, pyqt is generally easy to work with. For c++, you have choices like Qt (multiplatform), Quartz (Mac, with Objective C or Swift), etc.
Is there anyway to take an opencv display window and save it to a GUI window?
