I've some stuff that I did that was basicly reverse engineered from what little knowledge that I have regarding the subject and some c++ code of a very domain specific application that one of my professors did.

Mailing Address tokenization/elementization to individual components (street, city, etc.)

I need to parse international addresses to its individual components (street, city, etc.). After some reasonable survey, I found that HMMs/CRFs are the way to go.

HMM for perspective estimation in document image, can't understand the algorithm

Hello! Here is a paper, it is about estimating the perspective of binary image containing text and some noise or non text objects. PDF document The algorithm uses the Hidden Markov Model: actually two conditions T - text B - backgrouond (i.e. noise) It is hard to understand the algorithm itself. The question is that I've read about...
