Chapter 10. Debugging and Testing

We have come a long way since the start of our computer vision journey with OpenCV 3 and Qt5 Frameworks. We can now very easily install these powerful frameworks and configure a computer running a Windows, macOS, or Linux operating system so that we can design and build computer vision applications. Over the course of the previous chapters, we learned how to use the Qt plugin system to build modular and plugin-based applications. We learned how to style our apps using Qt Style Sheets and also make them support multiple languages by using the internationalization technologies in Qt. We built powerful graphics viewer applications using the Qt Graphics View Framework. The classes in this framework helped us deal with displaying graphical items much more efficiently and with much more flexibility. We were able to build graphics viewers that could zoom in and out of images without having to deal with the source image itself (thanks to the Scene-View-Item Architecture...
