Computer Vision with OpenCV 3 and Qt5

Camera and video handling in Qt

Since we are going to use OpenCV interfaces for handling images, cameras, and videos, we are not going to cover all of the possibilities that the Qt framework provides in order to read, view and process videos. But sometimes, especially when one of the two frameworks provides a better or simpler implementation of a feature, it really becomes too tempting to avoid it. For example, even though OpenCV provides very powerful methods for working with cameras, as we'll see in Chapter 12, Qt Quick Applications, Qt still has a lot to say when it comes to handling cameras on Android, iOS, and mobile platforms in general. So, let's see a brief introduction to some of the important and existing Qt classes for the camera ...
