Overview of the Software
InftyReader is a powerful application that recognizes scientific documents, including
mathematical expressions. It was developed at the Masakazu Suzuki Laboratory,
Graduate school of Mathematics, Kyushu University in collaboration with several
partners.
The software recognizes page images scanned at 600 DPI. Source image files must
be in TIF, PNG, or GIF formats.
InftyReader outputs recognition results in various formats including: IML, LaTeX, HRTeX, XHTML(MathML) and MS Word document(XML).
IML is a XML file format relates to InftyEditor, an editor of mathematical documents
developed and released by Science Accessibility Net.
Using InftyEditor, users can correct and edit the recognition results by comparing
them to the original images.
HR-TeX is a simplified LaTeX-like notation that is easier "to read" and specially
designed for individuals who are blind.
XHTML output displays mathematical expressions using MathML notation.
Key Features of InftyReader:
1. InftyReader uses the OCR engines from Toshiba Corporation,
"ExpressReaderPro", and MediaDrive Corporation’s "WinReader",
simultaneously to recognize characters in ordinary text areas. Characters and
math symbols in formulae, uses InftyReader’s OCR engine.
2. InftyReader can recognize tables including math expressions in the cells.
3. InftyReader can convert PDF files into LaTeX or XHTML(MathML) including
mathematical expressions. It recognizes the page images of PDF files
referencing the text information embedded in PDF.
Important Notes:
1. The source documents have to be clearly printed.
2. They should be scanned in 600dpi or 400dpi.
3. InftyReader erases small noises, segments page images into picture areas,
table areas and text areas automatically, and then recognizes text and table
areas including mathematical expressions. However, to get better recognition
results, users are <<recommended>> to erase noises and pictures before the
recognition.
4. In binary scanning, it is important to adjust the binarization threshold of the
scanner so that the number of the touched or broken characters is less than
1% of the total number of the characters in each scanned page image.
Operating Environment
InftyReader runs on Windows XP, Windows Vista, Windows 7 and Windows 8, if the
PC is equipped with enough memory. Note: InftyReader does not run on Windows
98, 2000 nor Me.
How to use InftyReader
1. Select the input file(s) or folder.
2. Select the Input/select output document name.
3. Press the "Start" button.
The recognition results of the selected image will then be saved iin the file format you
selected. When, you select a folder instead of files, all the image files in the folder of
the specified file type (TIF/GIF/PNG/BMP/PDF) are recognized and the results are
output as files having the same name(s) of the folders.
If you "Search Sub Folders" item under the "Option" menu, InftyReader recognizes
all the image files in the sub folders. For example, if you select the folder "foldertop"
having the subfolder structure below,
Top Folder
|-- subfolder1
| |-- a.tif
| |-- b.tif
|-- subfolder2
|-- c.tif
|-- d.tif
and you select the file type "IML" for the output file type, 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) will be saved in the file subfolder1.iml (resp.
subfolder2.iml).
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.
