OmniPage Zone OCR

Note: This process requires the purchase of a Quick Fields add-on.

This process performs Optical Character Recognition (OCR) to generate text from a specified area of the image. It can be used in Pre-Classification Processing, Identification, Page Processing or Storage Processing. You can draw or specify the coordinates of a box in a particular area of a sample image, and text will be extracted from that area of all the images processed with that OmniPage Zone OCR process. This text, in turn, can be used in a number of different ways. The most common ways to use information extracted from an image via OmniPage Zone OCR are to identify documents and automatically populate fields. OmniPage Zone OCR can also be used to name documents and create folders.

Example: The City of Wonderland configures a session to process building permit applications. Though they are mixed in with other documents, the applications all have "Building Permit Application" written at the top. They create a document class called "Permit Application" and configure an OmniPage Zone OCR process in the Identification tree item to generate text from a region at the top of the page and identify it as belonging to the class if it contains the words "Building Permit Application" at the top.

Example: The City of Wonderland also wants to retrieve other information from the building permit applications and insert it into the fields. They create OmniPage Zone OCR zones in the regions that contain the date and the name of the applicant and insert tokens representing those zones into the document fields. When the documents are processed, the data will be automatically entered into the fields.

To use OmniPage Zone OCR

1. In the Session Configuration Pane, select the stage of processing where you want to use OmniPage Zone OCR.
2. In the Tasks Pane, select OmniPage Zone OCR. Under More Options, you can select Wizard to display more information about each property or Skip Wizard to display the properties all at once without additional information.
3. Page Range: When configuring a process in Page Processing or Storage Processing, you will be prompted to specify a page range. In other stages, default settings will be automatically applied.
4. Region Selection: Define one or more regions, or zones, to be read by the OmniPage Zone OCR process.
• To define a region, drag and resize the zone on the Display Pane or specify coordinates in the Tasks Pane.  
• Specify a name for the region. This will also be the name of the token that represents the value read from the region.
• To define an additional region with the same settings, click Add again.
• To remove a region, select it and click Remove.
• To configure advanced OCR options for a specific region, select the region and click Advanced options. More info.
5. Identification Condition: When configuring OmniPage Zone OCR in Identification, you will be promoted to set an identification condition to match the information read from the region with the definitions for the document class.
6. Language Selection: Select a language to help optimize the character recognition.
7. Optimization: Specify an optimization style. There is generally a trade-off between speed and accuracy.

• Speed: Reduces the amount of time it takes to OCR. Generated text may be less accurate.
• Standard: Neither optimum speed nor optimum accuracy, but between the two.
• Accuracy: Increases OCR quality. Processing time will also be increased.

8. Orientation: Specify the zone's orientation. If a captured document's text in the zone matches this setting, OCR will be more accurate.

   Tip: 0 degrees represents a standard page with text that reads from left to right. 180 degrees represents a page that appears upside down.

9. Optional: To preview how this enhancement will affect scanned images and OCRed or extracted text, test processes. For the best results, add a custom sample image before testing. Adjust and test until you are satisfied with the results.
