Public Domain OCR

NIST FORM-BASED HANDPRINT RECOGNITION SYSTEM (RELEASE 2.2)

A public domain document processing system was developed by the National Institute of Standards and Technology (NIST) in 1994. The system is a standard reference form-based handprint recognition system for evaluating optical character recognition (OCR), and it is intended to provide a baseline of performance on an open application. 

NIST developed a new release in 2003 for internet distribution of its standard reference form-based handprint recognition system for evaluating optical character recognition (OCR). Release 2.2 incorporates all bug fixes generated for previous versions.
