ABBYY FineReader allows you to use patterns to improve OCR
quality.
On the Tools menu, click Pattern Editor….
In the Pattern Editor dialog box, select the desired
pattern from the list of available patterns and click Set
Active.
Some important points to remember:
Rather than differentiating between some similar yet different
characters, ABBYY FineReader recognizes them as one and the same
character. For example, the straight ('), left (‘), and right
(’) quotes will be stored in a pattern as a single character
(straight quote). This means that left and right quotes will never
be used in the recognized text, even if you try to train them.
For some character images, ABBYY FineReader will select the
corresponding keyboard character based on the surrounding context.
For example, an image of a small circle will be recognized as the
letter O if there are letters immediately next to it and as the
number 0 if there are digits next to it.
A pattern can only be used for documents that have the same
font, font size, and resolution as the document used to create the
pattern.
To recognize texts set in a different font, be sure to disable
the user pattern by selecting the Use only built-in patterns
option in Tools>Options…>Read.
