Hello all, I just wanted to ask if anyone knew of some good reference/learning material for programming letter recognition algorithms?

Thanks,

By letter recognition algorithms, are you talking about image comparison algorithms? I found a good article you may find helpful.

Coursera has a Machine Learning course in which one of the programming assignments is to do handwriting recognition. It's a pretty involved process, but at it's core we use one-vs-all classification atop logistic regression and gradient descent. A neural network is a more powerful, but complex model that can be used for classification.

For Coursera, we use GNU Octave, for it's vector processing abilities, but the concepts taught are language agnostic. You also might want to check out the following texts:
