Conventions

In this book, you will find a number of text styles that distinguish between different kinds of information. Here are some examples of these styles and an explanation of their meaning.

Code words in text, database table names, folder names, filenames, file extensions, pathnames, dummy URLs, user input, and Twitter handles are shown as follows: "You should put most of the code from this chapter into the cartoonifyImage() function"

A block of code is set as follows:

    int cameraNumber = 0;
    if (argc> 1)
      cameraNumber = atoi(argv[1]);
    // Get access to the camera.
    cv::VideoCapture capture

When we wish to draw your attention to a particular part of a code block, the relevant lines or items are set in bold:

    // Get access to the camera.
    cv::VideoCapture capture;
 camera.open(cameraNumber);     if (!camera.isOpened()) {
      std::cerr<< "ERROR: Could not access the camera or video!" <<

Any command-line input or output is written as follows:

cmake -G "Visual Studio 10" 

New terms and important words are shown in bold. Words that you see on the screen, for example, in menus or dialog boxes, appear in the text like this: "In order to download new modules, we will go to Files | Settings | Project Name | Project Interpreter."

Warnings or important notes appear in a box like this.

Tips and tricks appear like this.
