Pre-processing before digit recognition with KNN classifier

Question

Right now I\'m trying to create digit recognition system using OpenCV. There are many articles and examples in WEB (and even on StackOverflow). I decided to use KNN classifier b

Answer 1

I can not give you a better answer than your own answer, but I would like to contribute with an advise. You could improve your digits recognition system on the following way:

• Apply over the white and black patch an skeletonization process.

• After that, apply distance transform.

On this way you can improve results of the classifier when digits are not exactly centered or they are not exactly the same, morphologically speaking.
