Break Captchas! (April to May)
General Information
Welcome dear Coders and AI-Fans,
this is the very first competition we are launching. As described earlier, the competition will consist of two parts. The first part are a few tutorials, which match exactly to the topic of the competition or at least may be usefull. This time we prepared three tutorials for you, which may help you and guide you through your first program. In this competition the tutorials will be available in german and english as text. In future competitions there may be also videos and "programs" to teach you the basics.
The first subject we want to focus on is: Cracking Captchas
Huh? Sounds like an interesting and extremely complex subject, does it not? You are asking how you should ever be able to create something, which would crack a captcha? Well today you will learn it! This time we are going to break a few quite simple but still "realistic" captchas with not as much code and brainpower as you may think!
If you did not hear of the word "Captcha" before, let me summarize Captchas as "a script to distinguish between bots and humans by letting the user solve an intelligent task". If this still does not ring a bell to you, have a look at these examples:

These are all Captchas, to be more precise these are all text captchas. This competition will focus on breaking simple number captchas. But you will learn a lot of things, which easily can be applied to breaking complex captchas, too.
We will choose handwritten captchas containing only numbers with a length of minimum of three digits up to five digits. A few example captchas, which also will be provided as examples in the download section later on:
