Preprocessing Images - ScanSoft OMNIPAGE 15 Manual

Form
Choose this if your whole page consists of a form and you want
form elements auto-recognized. After recognition, you can
modify form element properties, create new ones, or edit form
layout. This option is available in OmniPage Professional 15
only.
Custom
Choose this for maximum control over auto-zoning. You can
prevent or encourage the detection of columns, graphics and
tables. Make your settings in the OCR panel of the Options
dialog box.
Template
Choose a zone template file if you wish to have its background
value, zones and properties applied to all acquired pages from
now on. The template zones are also applied to the current
page, replacing any existing zones.
If auto-zoning yielded unexpected recognition results, use manual
processing to rezone individual pages and re-recognize them.

Preprocessing Images

To improve OCR results, you can enhance your images before zoning and
recognition using the Image Enhancement tools. To open the Image
Enhancement window, click the Enhance Image button in the Image
Toolbar, or click Tools and choose Enhance Image. You can also build
Image Enhancement steps into your workflows by choosing the Enhance
Images step.
The input for Image Enhancement is the Primary image.
We must distinguish three types of image:
Original image: The image created by your scanner or contained in a file
before it enters the program.
