Training to recognize a character:
The frame in the top dialog window should enclose
a single character, and this character
must be fully enclosed by the frame. If the frame encloses only part of a character or
more than one character, click the frame borders and move them so that the abovestated
requirements are met. The and buttons move the frame border as well (and are
useful for training italic symbols – see below). Once you have positioned the frame correct
ly, type in the character and click the
Train button.
Note: 1. You may only train the system to read characters included in the alphabet.
If you wish to train FineReader to read characters that cannot be entered from
the keyboard, use a combination of two characters to denote these nonexis
tent characters or copy the required character from the
Character Table
(click the button in the Pattern Training dialog to open the Character
Table
).
2. If you wish to train the system to retain character formatting, select the cor
responding
Italic or Bold item in the Pattern Training dialog before
clicking the
Train button.
3. Make sure that only uppercase/lowercase characters are entered when train
ing uppercase/lowercase character images respectively.
If you make a mistake during training, click the Back button to return the frame to its pre
vious position. The last “imagecharacter” pair to be entered will automatically be removed
from the pattern. Note that this “undo” function is limited to the last word trained.
Training to recognize ligatures
A ligature is a combination of two or three “glued” characters, for example, fi, fl, ffi, etc.
These characters are difficult to separate because they are “glued” as part of the printing
process. In fact, better results can be obtained by treating them as “single” compound char
acters.
Training ligatures is no different to training separate characters:
1. Type in the desired 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. However, avoid creating too many lig
atures, as it may have an adverse effect on recognition quality.
Always take the following into account when training FineReader:
1. FineReader does not differentiate between certain characters that are nor
mally considered different. For example, the straight (
|
), right (
/
) and left (
\
)
