In this chapter, we learned the basics of how to access images and videos and how they are stored in matrices.
We learned the basic matrix operations and other basic OpenCV classes to store pixels, vectors, and so on.
Finally, we learned how to save our data in files to allow them to be read in other applications or executions.
In the next chapter, we will learn how to create our first application by learning the basics of a Graphical User Interface that OpenCV gives us. We will create buttons and sliders and introduce some image processing basics.
