9. Examples of Recognition Results by InftyReader

1. About 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 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. 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.

2. Minimum System Requirements top

• Windows XP SP2;

• 500 MB (or more) system memory;

• Internet Explorer Version 6 or greater;

• Please note: InftyReader does not run on Windows 98, Me, 2000.

3. Maximizing the use of InftyReader top

1. All source documents must be clearly printed.

2. All images need to be "binary" images of, preferably, 600 DPI.  Scanning documents at 400 DPI is possible.  However, the accuracy of the results will not be as good as documents scanned at 600 DPI.

3. 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.

4. To get better recognition results, users are encouraged to delete all markings from documents before OCR'ing them with InftyReader.

5. 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
