Abstract

Effective character recognition algorithms are optimized to NOT be influenced by the font of the characters. Recognition is based on invariant characteristics of the letters. Published information contains more information than the simple text. Headings, footnotes references, EMPHASIS.. can be denoted by change in font and size.

Use of Non-predominate Color for Font Recognition

       Effective character recognition algorithms are optimized
to NOT be influenced by the font of the characters.  Recognition is
based on invariant characteristics of the letters.  Published
information contains more information than the simple text. Headings,
footnotes references, EMPHASIS.. can be denoted by change in font and
size.

      This article extends the prior art to also encode font
information by non-obvious colors selected during printing.

      Extend the definition from prior art of colors such that a
relative combination uniquely defines letters but the total
saturation defines a font.  This will enable all letters printed in
the same font to be similar in hue while still unique in R/B/G
relative percentages.
