and myself):
This code is a raw OCR engine. It has NO PAGE LAYOUT ANALYSIS, NO
OUTPUT FORMATTING, and NO UI. It can only process an image of a
single column and create text from it. It can detect fixed pitch
vs proportional text. Having said that, in 1995, this engine was
in the top 3 in terms of character accuracy, and it compiles and
runs on both Linux and Windows. Another current limitation is that
it only recognizes English and its character set is only US-ASCII.
Training code IS included in the open source release however, and
will be included in a future release.
