I am working on a handwriting recognition android application project. I should recognize characters by online recognition.(I mean there are no words or images). I searched lots of websites about it. I learned that I would use neural network and I also learned how I can use neural network. But, I am confused about how I can set neural network by using inputs from user. Should I use points of characters or turn the characters into image? And then how can I create neural network by just using this inputs?
