This chapter started with an explanation of how to build and install the OpenCV library with Qt (using CMake, the GNU g++ compiler, and GNU Make). Then, it is given a quick look to the modules organization of the library with an easy explanation of its basic API concepts. The chapter follows up with a more detailed revision of the fundamental data structures to store arrays and manipulate images. Also, three examples of code, such as flipImage
, showVideo
, and recLiveVid
are explained to illustrate the basic use of the OpenCV library. The next chapter will introduce you to the two mainstream options available to provide graphical user interface capabilities for OpenCV programs.
