-   @subpage tutorial_table_of_content_introduction

    You will learn how to setup OpenCV on your computer

-   @subpage tutorial_table_of_content_core

    Here you will learn
    about the basic building blocks of this library. A must read for understanding how
    to manipulate the images on a pixel level.

-   @subpage tutorial_table_of_content_imgproc

    In this section
    you will learn about the image processing (manipulation) functions inside OpenCV.

-   @subpage tutorial_table_of_content_highgui

    This section contains valuable tutorials on how to use the
    built-in graphical user interface of the library.

-   @subpage tutorial_table_of_content_imgcodecs

    These tutorials show how to read and write images using imgcodecs module.

-   @subpage tutorial_table_of_content_videoio
