Features for Handwriting Recognition

In the following page you could find tools for computing several features for handwriting recognition.
Feature Extraction Tools.

iATROS (Improved ATROS)

iATROS is a new implementation of a previous speech recogniser that has been adapted to be used in both speech and handwritten text recognition. iATROS provides a modular structure that can be used to build different systems whose core is a Viterbi-like search on a Hidden Markov Model network. iATROS provides standard tools for off-line recognition and on-line speech recognition (based on ALSA modules).

Thot: a toolkit for phrase-based statistical machine translation

Thot is an open source toolkit for statistical machine translation. Originally, Thot incorporated tools to train phrase-based models. The new version of Thot now includes a state-of-the-art phrase-based translation decoder as well as tools to estimate all of the models involved in the translation process. In addition to this, Thot is also able to incrementally update its models in real time after presenting an individual sentence pair. Download
