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.
Click the SET - Enhance Image button in the Image Toolbar to open the Image
Enhancement window. This window has a starting image panel (1) on the left and a result
panel (2) on the right. Choose a tool (see following topics), then move sliders and adjust
controls (3). When the result is good, click Apply (4). Discard last change (5) or Discard all
changes (6) provide emergency exits. When you click Apply, the result image moves to the
left panel to become the new starting image for further enhancement. Changes are listed in the
History panel (7). When all changes are in order, click Page Ready (8) to have the next page
loaded or Document Ready (9) to finish enhancing.
