Unconstrained Handprint Recognition Using a Limited Lexicon

摘要

A word recognition system has been developed at the National Institute of Standards and Technology (NIST) to read free-formatted text paragraphs containing handprinted characters. The system has been developed and tested using samples of handprint from NIST Special Database 1. This database of binary images contains 2,100 different writers' printings of the Preamble to the U.S. Constitution. Each writer was asked to print these sentences in an empty 70mm by 175mm box. The Constitution box contains no guidelines for the placement and spacing of the handprinted text, nor are there guidelines to instruct the writer where to stop printing one line and to begin the next. This paper discusses the word recognition system in detail.
