* Comments about output formats
- IML is the default XML file format of the editor "InftyEditor", an authoring tool of math documents developed by InftyProject. InftyEditor provides a very easy user interface to input and edit math expressions together with ordinary texts.
The English edition of InftyEditor is a free software. Please see the sites of InftyEditor.
- In XHTML format, mathematical expressions are output using MathML notation.
- HR-TeX is a simplified LaTeX-like notation easier "to read" specially
designed for the blinds.
Using InftyEditor, user can correct and edit the recognition results of InftyReader comparing the results with original images, and convert the results into various formats: LaTeX, PDF, XHTML with MathML, etc.
Please note that InftyReader recognizes only <<Black and White>>, <<Binary>> images carefully scanned in either 600DPI or 400 DPI. Please be aware that the program fails to run if the imput image contains gray scale image areas or color image areas even partly.
Image files have to be prepared in either TIFF, PNG, or BMP format. InftyReader recognizes also PDF. It converts input PDF to PNG file first and then recognizes the converted image files.
Here are some features of InftyReader since Ver. 2.8 :
- It uses the OCR engines of Toshiba Corporation, "ExpressReaderPro", and of MediaDrive Corporation, "WinReader", simultaneously to improve the recognition results of characters in ordinary text areas. (As for the characters and math symbols
in formulae, it uses Infty's OCR).
- It can recognize tables including math expressions in the cells (in case the ruled lines are not broken),
- It can convert PDF files into LaTeX or XHTML(MathML) including
mathematical expressions, except for PDF including color images or gray
images. (Note that InftyReader can process only black and white binary images)
It recognizes the page images of PDF files refering to the text information
imbedded in PDF.
Attention: The original PDF should be of high resolution equivalent to 600dpi scanned images. Someimes PDF files existing on the WEB are of low resolution of the level 200dpi images, in order to reduce those file sizes. In such cases, the recognition results will be of very low quality of the level almost useless!
* Caution ---- Important!
- Source documents have to be clearly printed.
- It should be scanned in in 600dpi (or 400dpi). Usualy, binary images are better for the recognition than color images.
- InftyReader erases small noises, segments page images into picture areas,
table areas and text areas automatically, and then recognizes text/table
areas including mathematical expressions.
However, to get better recognition results, users are <<recommended>>
to erase noises and pictures before the recognition.
- In 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 8, Windows 7, Vista, XP, on a PC equipped with 1GB free memory or more.
Note that it does not run on Windows 98, Me, nor 2000. .
* How to use InftyReader?
- Select file(s) or folder.
- Input/select output docuent name
- Press the "Start" button.
Then, the recognition results of the selected image files are saved in to the file you specified by the "output docuent name". 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
into the 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
| |-- a.tif
| |-- b.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.
