In this tutorial, there is a link to empty file. I cannot find the file and its name. I can make the functions but I am missing the main function code.
http://docs.opencv.org/3.1.0/df/d61/tutorial_random_generator_and_text.html
I would like to ask one more question. Can you recommend me more examples, which somebody written for public domain using OpenCV? More effects which are not included in tutorials and OpenCV examples? For example I would like to know how to create exactly same effect: https://en.wikipedia.org/wiki/Sobel_operator#/media/File:Valve_sobel_%283%29.PNG also I am interested about reading (analysing of image shapes) so more examples which are not covered but if you know some good stuff to check out. I am using Windows XP and Visual Studio 2010. Thanks
