Computer Vision with OpenCV 3 and Qt5

Main modules

Here are some examples of OpenCV main modules. Note that they're just a few (and probably the most widely used) of modules within OpenCV, and covering all of them is out of the scope of this book, but it makes sense to have an idea of what OpenCV contains, just like what we saw with Qt earlier in this chapter. Here they are:

• Core functionality or simply core module contains all basic structures, constants, and functions used by all other OpenCV modules. For instance, the infamous OpenCV Mat class, which we'll use almost in every OpenCV example for the rest of the book, is defined in this module. Chapter 4, Mat and QImage, will cover this and closely-related OpenCV modules along with corresponding parts of the Qt framework.
