What to include in an OpenCV C + + program?

These concepts will help you to understand and write OpenCV C++ example programs in this tutorial more easily. You will need to include only the opencv2/opencv.hpp header file in your program. That header file will include all the other necessary header files for your application.

Where are OpenCV classes and functions in CV namespace?

All OpenCV classes and functions are in cv namespace. So, you have to do one of following Add the using namespace cv; line just after including header files (I have used this method in all my example programs in this tutorial)

What do you mean by transparent API in OpenCV?

It is called the Transparent API ( T-api or TAPI ). What is Transparent API ( T-API or TAPI )? The Transparent API is an easy way to seamlessly add hardware acceleration to your OpenCV code with minimal change to existing code. You can make your code almost an order of magnitude faster by making a laughably small change.

Where do the header files go in OpenCV?

That header file will include all the other necessary header files for your application. Therefore you don’t need to bother thinking which header files should be included for your program any more. All OpenCV classes and functions are in cv namespace. So, you have to do one of following
