Improving OCR Results

OmniPage Pro has many features that allow you to customize

processing and improve OCR results. Please refer to the online Help for

more information on these and other ways to improve OCR results.

Adjusting Page Images Before OCR

You can rotate and straighten page images in OmniPage Pro’s image

view before zoning and OCR take place. This is recommended to

improve OCR accuracy on pages that are not oriented correctly.

If you need to rotate or straighten a page, be sure to do so

before

performing OCR because all zones are deleted during these operations.

To rotate a page image:

1 Click on the page image to make the image view active.

2 Click the Rotate Image button to rotate the image 90-degrees

(clockwise) at a time.

Or, choose

Rotate

in the View menu and select 90, 180, or 270

degrees.

To straighten a page image:

1 Click on the page image to make the image view active.

2 Click the Straighten Image button.

Or, choose

Straighten Image

in the View menu.

OmniPage Pro straightens the page image up to a maximum of

10 degrees. OmniPage Pro will not straighten a page if it

determines that it is unnecessary.

It is recommended that you have OmniPage Pro automatically

rotate or straighten pages if needed during OCR by simply selecting

the

Automatically straighten page image

and

Automatically correct page

orientation

options in the

Process

tab of the Options dialog box.
