2. The system can be trained to retain character formatting. Select the corre
sponding Italic or Bold item in the Pattern Training dialog and then click
the Train button.
3. Training is case sensitive. During training, make sure that you use upper or
lower case characters as appropriate.
Correct mistakes made during training by clicking the Back button to return the frame to its
previous position. The last “imagecharacter” pair to be entered will automatically be removed
from the pattern. The “undo” function is limited to the last word trained.
Training to recognize ligatures
Ligatures, which are a combination of two or three “glued” characters (such as fi, fl, ffi, etc.),
are difficult to separate because they are “glued” as part of the printing process. Better results
can be obtained training the software to recognize the compound characters as a single
unique character.
Train the same way that you would train separate characters:
1. Type the necessary character combination and click the Train button.
2. The frame in the top dialog window should enclose the entire ligature.You
can move the frame border using the mouse or by clicking the and
buttons.
Each pattern may contain up to 1000 new characters. Limit the number of ligatures that you
train, since these characters may lower recognition quality.
When you train ABBYY FineReader, please remember:
1. ABBYY FineReader doesn’t differentiate between certain characters that are
unique to the human eye. These multiple characters will be categorized
together and assigned a certain character. For example, the straight (‘), right
(‘) and left (‘) apostrophes are all identified as a single character – the straight
apostrophe. These characters will never appear in recognized text even if you
try to train them.
2. The recognition of some characters depends on their environment.
How to Edit a User Pattern
You may want to edit your newly created pattern before you begin recognition, since an incor
rectly trained pattern will reduce recognition quality. Remove characters with cut edges and
incorrectly labeled characters from the pattern.
