Chapter 3. Learning the Graphical User Interface and Basic Filtering
In the previous chapter, we learned the basic classes and structures of OpenCV and the most important class called
We learned how to read and save images, videos, and the internal structure in the memory of images.
We are ready to work now, but we need to show our results and have some basic interaction with our images. OpenCV provides us with a few basic user interfaces to work with and help create our applications and prototypes.
To better understand how the user interface works, we are going to create a small application called PhotoTool at the end of this chapter. In this application, we will learn how to use filters and color conversions.
In this chapter, we will cover ...
