Reading Images
Explore how to read and display images using OpenCV in C++. Learn to include necessary headers, handle namespaces, load images with imread, show them with imshow, and control display timing using waitKey. This lesson builds a foundation for image handling in computer vision applications.
We'll cover the following...
Header files and namespaces
Header files in C++ are used to declare functions, classes, and variables that are defined in a separate source file. These header files provide a way to separate the interface of a program from its implementation, making it easier to organize and maintain large code bases. We’ll use only one header file, opencv.hpp, for this lesson. This header file contains all the necessary functions used in OpenCV.
To include the code, we need to use the include keyword and also include the path to the file. In the code below, the header file is located in the opencv2 ...
