The program you provided is achieved by using third parties,
I need a code example of the algorithm, or preferably an available component. Peter Thanks Simpson.

I think what you are looking for is referred to as character recognition.

This is a huge field of study – definitely not an easy task.

A few months ago I remember seeing code for license plate recognition in OpenCV. A lot of the source code is available for algorithms written using OpenCV and there are tutorials and examples available. I'm not sure about the license plate recognizer. You should be able to find it doing a Google search.

Some time ago, I've started to think about that...there is a java ocr project which have to be wrapped into a library for b4a:
