Chapter 2. Handling Files, Cameras, and GUIs
This chapter introduces OpenCV's I/O functionality. We also discuss a project concept and the beginnings of an object-oriented design for this project, which we will flesh out in subsequent chapters.
By starting with a look at I/O capabilities and design patterns, we are building our project in the same way we would make a sandwich: from the outside in. Bread slices and spread or endpoints and glue, come before fillings or algorithms. We choose this approach because computer vision is extroverted—it contemplates the real world outside our computer—and we want to apply all our subsequent, algorithmic work to the real world through a common interface.
