Summary

In this chapter, you were introduced to the concept of Computer Vision in general and to the Qt and OpenCV frameworks, and you learned about their overall modular structure and also got a brief look into how seriously cross-platform they are with all the platforms they both support. You also learned how to install Qt on a computer and how to build OpenCV using its source codes. By now, you should have enough confidence to even try out a few different configurations to build OpenCV, other than the standard build mentioned in this chapter. It's always a good idea to explore some unknown and deep parts of these huge frameworks by simply taking a look in the folders and files they contain. Finally, you learned how to configure your development computer to build applications using Qt and OpenCV, and you even built your first application. In the next chapter, you'll learn more about Qt Creator by first building a console application and then moving on to building a Qt widgets application. You'll also learn about the structure of Qt projects and how to create a cross-platform integration between Qt and OpenCV frameworks. The next chapter will be the start of actual computer vision development and programming examples in this book and will lay out the foundations of our hands-on examples throughout the book.
