Welcome to InftyReader Group, Inc.
"When it comes to
understanding math well enough to make it fully accessible, there are
three types of people in the world. Those who understand how to do
it and those who don't."

1. What is InftyReader?
Top
InftyReader is an
Optical Character Recognition (OCR) application that
recognizes and translates scientific documents (including math symbols) into
LaTeX,
MathML and
XHTML!
InftyReader can recognize tables including math expressions in the cells so
long as the ruled lines are not broken.
InftyReader recognizes and translates print documents. It is capable,
believe it or not, to perform the following conversions:
-
BMP images into
LaTeX files;
-
BMP images into
MathML files;
-
GIF images into LaTeX files;
-
GIF images into MathML files;
-
PDF iles into LaTeX files;
-
PDF images into MathML files;
-
PNG
images into LaTeX files;
-
PNG images into
MathML files;
-
TIFF images into LaTeX
files;
-
TIFF images into MathML files;
InftyReader incorporates the use of three OCR engines. The first is InftyReader's
own OCR engine which has been designed to recognize
scientific and mathematical symbols in formulae. The second and third OCR engines are
from the Toshiba Corporation (ExpressReaderPro) and MediaDrive Corporation (WinReader).
The ExpressReaderPro and WinReader OCR engines operate simultaneously in order to improve the
recognition results of characters appearing in ordinary text areas.
Please Note: InftyReader does not convert PDF files containing
gray-scale or color images. Once, again, InftyReader can only process
black and white images (binary images). Original PDF documents
must contain high resolution 600 Dots per inch
(DPI) scanned images in order for InftyReader to work effectively.

Our InftyReader
demo package contains three, separate, files all of which need to be
downloaded and installed into the
same folder. The package includes:
About DicKits:
If you
installed InftyReaderDicKit A and B for InftyReader V2.6.0 or InftyReader
V2.6.1, please uninstall them before installing the
new DicKits for Version 2.6.4. The dictionaries themselves are the same, but the
installing folder and the properties of the folders will be changed by the new
installer.
-
InftyReader Markup
Language (IML) is the
default XML file format of InftyEditor, which is an authoring tool for math
documents. InftyEditor provides a user-friendly interface to input and edit
math expressions together with ordinary texts.
-
The
English edition of InftyEditor is free software.
-
In XHTML
format, mathematical expressions are output using MathML notation.
-
HR-TeX is
a simplified LaTeX-like notation designed to be easier to read, especially
for individuals who are blind.
-
InftyEditor was designed to correct and edit the recognition results from
InftyReader.
-
Important note:
InftyReader only recognizes
Black and White (binary) images
scanned at
600 DPI. InftyReader does not scan
or convert gray scale, or color, image areas. Image files have to be prepared in either
a TIFF,
GIF,
PNG, or
BMP format.

Guidelines for maximizing the effectiveness of InftyReader
Top
-
All source
documents must be clearly printed.
-
All images need
to be "binary" images scanned at 600 DPI.
-
InftyReader eliminates noise (smudges, pencil marks, some highlights, etc.) so long as
they are minor and do not cover any of the text being scanned.
-
To get
better recognition results, users are encouraged to delete all markings from
documents before OCR'ing them with InftyReader.
-
Adjust the
binarization threshold of the scanner you are using so that the number of the
touched or broken characters are less than 1% of the total number of the
characters in each scanned page image. If this is not done the accuracy
of the results will be negatively impacted.
8.
Getting Started
Top
-
Select
file(s) or folder.
-
Input/select output document name
-
Select your
options
-
Press the
"Start" button.
The
results of the OCR'd image files are saved to the file specified in the "output document name"
field. When you select a folder instead of
a files, all the image files in the folder of the specified file type (TIF/GIF/PNG/BMP/PDF)
are recognized. The results are then output as files having the name(s) of
the folders.
If you set
check to the "Search Sub Folders" item under the "Option" menu, InftyReader
recognizes all the image files in the sub folders of the selected folder. For
example, if you select the folder "foldertop" having the subfolder structure
below,
foldertop
|-- subfolder1
| |-- a.tif
| |-- b.tif
|
|-- subfolder2
|-- c.tif
|-- d.tif
and if you
select the file type "IML" for the output file type, then, you will get the
files "subfolder1.iml", "subfolder2.iml" in the folder "foldertop". The
recognition results of a.tif and b.tif (resp. c.tif and d.tif) are saved in the
file subfolder1.iml (resp. subfolder2.iml, respectively).
If you
select LaTeX as output file type, you will get "subfolder1.tex",
"subfolder2.tex", and it is similar for other file types HR-TeX and XHTML.
