Training
Training is the process of changing the OCR solutions assigned to character shapes in the
image. It is useful for uniformly degraded documents or when an unusual typeface is used
throughout a document. OmniPage offers two types of training: manual training and
automatic training (IntelliTrain). Data coming from both types of training are combined and
available for saving to a training file.
When you leave a page on which training data was generated, you will be asked how to apply
it to other existing pages in the document.
Manual training
To do manual training, place the insertion point in front of the character you want to train, or
select a group of characters (up to one word) and choose Train Character... from the Tools
menu or the shortcut menu. You will see an enlarged view of the character(s) to be trained,
along with the current OCR solution. Change this to the desired solution and click OK. The
program takes this training and examines the rest of the page. If it finds candidate words to
change, the Check Training dialog box lists these. Incorrect words should be re-trained before
the list is approved.
IntelliTrain
IntelliTrain is an automated form of training. It takes input from the corrections you make
during proofing. When you make a change, it remembers the character shape involved, and
your proofing change. It searches other similar character shapes in the document, especially in
suspect words. It assesses whether to apply the user correction or not.
You can turn IntelliTrain on or off in the Proofing panel of the Options dialog box.
IntelliTrain remembers the training data it collects, and adds it to any manual training you
have done. This training can be saved to a training file for future use with similar documents.
For examples of IntelliTrain, see Help.
Training files
Whenever you close a document or switch to another one when unsaved training data exists, a
dialog box appears allowing you to save it. To save a training file into an OPD, load it from
Tools > Training File, click Embed, and save to the file type OmniPage Document.
