Handwritten digit recognition with ANNs

The world of Machine Learning is vast and mostly unexplored, and ANNs are but one of the many concepts related to Machine Learning, which is one of the many subdisciplines of Artificial Intelligence. For the purpose of this chapter, we will only be exploring the concept of ANNs in the context of OpenCV. It is by no means an exhaustive treatise on the subject of Artificial Intelligence.

Ultimately, we're interested in seeing ANNs work in the real world. So let's go ahead and make it happen.
