About InftyReader:

InftyReader is an Optical Character Recognition (OCR) application that recognizes and translates image-based 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 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.

InftyReader Enterprise Version License:

Important Note: In order to purchase an InftyReader Entrerprise license your organization will need to be pre-approved.

An InftyReader InftyReader license was designed for business/professional use in support of recognizing large volumes of pages. There is no limit to the number of pages that can be processed.

An InftyReader Enterprise license may be used to provide InftyReader network service to users on a campus or in one organization. It may not be used to accommodate an unlimited number of users.

An InftyReader Enterprise license may be used for the research and development purposes, e.g., extracting special functions of InftyReader such as the recognition of mathematical symbols and the recognition of math expressions assigning the specified subareas of a page imaege, etc..

Important Note:

InftyReader cannot process gray-scale/color images or pixelated images of characters. There should also be no background colors in the images being processed. InftyReader can only process black and white images (binary images).  Original images must be high resolution 600 Dots Per Inch (DPI) in order for InftyReader to work effectively. Web-based PDF files often contain low resolution images (<300 DPI) in order to reduce download and load times. In such cases, the recognition results will be useless.

InftyReader System Requirements:

  • Windows XP, Vista, Windows 7
  • 1 GB (or more) of system memory;
  • Internet Explorer
  • Note: InftyReader does not run on Windows 98, Me, or 2000.

Maximizing the Accuracy and Effectiveness of InftyReader:

  • All source documents must be clearly printed.
  • All images need to be “binary” images scanned at 600 DPI. InftyReader will eliminate “noise” (smudges, pencil marks, some highlights, etc.) so long as the “noise” is minor and does 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 percentage of the “noisy” or broken characters is 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
