As with the previous chapters, readers are required to have Qt of at least version 5 and OpenCV 4.0.0 installed. Having some basic knowledge about C++ and Qt programming is also a basic requirement.
Though we are focusing on OpenCV 4.0.0, OpenCV 3.4.x is also required in this chapter. You should have multiple versions (4.0.0 and 3.4.5) of OpenCV installed to follow along with this chapter. I will explain why later.
Since we will use deep learning models to detect objects, having knowledge of deep learning will also be a big help in understanding the contents of this chapter.
All the code for this chapter can be found in our code repository at https://github.com/PacktPublishing/Qt-5-and-OpenCV-4-Computer-Vision-Projects/tree/master/Chapter-06.
