InftyReader: Target Documents Printed books Images of equations PDF files that include image-based math expressions (not text-based expressions). Copyright 2008-2017 by InftyReader Group, Inc. All rights reserved.

Example: Text-Based Math Expression If you can select individual symbols with your mouse, you are looking at a text-based math expression. Copyright 2008-2017 by InftyReader Group, Inc. All rights reserved.

Text-Based Math Expression Extracted, text-based, math expressions are useless and meaningless when it comes to making math content accessible. Here’s what a text extraction of the math expression on the previous slide looks like: Y0 (t) = nX-1 j=1 Xj (y(t))dyj dt (t) Copyright 2008-2017 by InftyReader Group, Inc. All rights reserved.

Example: Image-Based Math Expression If you cannot select individual symbols with your mouse, you are looking at an image-based math expression. Copyright 2008-2017 by InftyReader Group, Inc. All rights reserved.

Example: Simple Layout Document Automatic conversion of simple layout documents is easy with InftyReader. For example: Copyright 2008-2017 by InftyReader Group, Inc. All rights reserved.

Example: Complex Layout Document. Automatic conversion of complex layout documents is not easy and normally requires a combination of automatic and manual actions. For example: Copyright 2008-2017 by InftyReader Group, Inc. All rights reserved.
