To get better recognition results, users are encouraged to delete all markings from documents before OCRвЂ™ing them with InftyReader. InftyReader will eliminate вЂњnoiseвЂќ (smudges, pencil marks, some highlights, etc.) so long as the вЂњnoiseвЂќ is minor and do not cover any of the text being scanned. All images need to be вЂњbinaryвЂќ images scanned at 600 DPI.All source documents must be clearly printed.Maximizing the Accuracy and Effectiveness of InftyReader:

Note: InftyReader does not run on Windows 98, Me, or 2000.

In such cases, the recognition results will be useless.

Web-based PDF files often contain low resolution images (<300 DPI) in order to reduce download and load times. Original PDF documents must contain high resolution 600 Dots per inch (DPI) scanned images in order for InftyReader to work effectively. Once, again, InftyReader can only process black and white images (binary images). InftyReader does not convert PDF files containing gray-scale, text, or color images.

The ExpressReaderPro and WinReader OCR engines operate simultaneously in order to improve the recognition results of characters appearing in ordinary text areas. The second and third OCR engines are from the Toshiba Corporation (ExpressReaderPro) and MediaDrive Corporation (WinReader). The first is InftyReaderвЂ™s own OCR engine which has been designed to recognize scientific and mathematical symbols in formulae. InftyReader incorporates the use of three OCR engines. InftyReader can recognize tables including math expressions in the cells so long as the ruled lines are not broken. InftyReader recognizes and translates image-basedВ scientific documents (including math symbols) into LaTeX, MathML and XHTML. Making math accessible would require authors to redraw images constantly,В even when small changes are made.Most math contentВ cannot, easily, be altered to accommodate the learning needs of students with low vision (color, font size, and contrast changes) and,.

Most math content cannot, easily,В be converted into alternative output modalities, such as Braille or synthetic speech.

Often, images of mathematical equations, appearing on web pages, in print, in eBooks, and PDF documents, are not accessible by students using Assistive Technology.

Why canвЂ™t some individuals with a print disability access mathematical content? Science, Technology, Engineering, and Math (STEM) documents may include any/all of the following: Print disabilities include visual impairments, learning disabilities, or physical disabilities that impede the ability to manipulate a book in some way. A print disability prevents a person from acquiring knowledge from printed materials in a standard way, and requires them to use alternative methods to access that information. InftyReader is an Optical Character Recognition (OCR) application designed to convert Science, Technology, Engineering, and Math (STEM) educational content (both digital and print formats) into LaTeX, MathML, and/or Word XML in support of K-20 students with print disabilities.ДЄ person with a print disability is an individual who cannot effectively read print because of a visual, physical, perceptual, developmental, cognitive, or learning disability.
