Add a mixed print page recognition profile

Recognition engines can recognize different types of fonts on a document when the print types are specified in their profile settings. The Mixed Print page recognition profile can combine two predefined recognition profiles to perform full page recognition by recognizing machine printed and hand written text.

For example, use Mixed Print page recognition for:

  • documents with machine printed text together with hand printed annotations

  • documents where the hand written characters cannot be located on a specific zone

  • documents where it is necessary to detect the signature

  • a batch of mixed documents with either hand or machine printed text such as receipts or prescriptions

The Mixed Print page recognition method recognizes all hand written text on a page, separates the entire text into segments (hand written or machine print) and then forwards these segmentation results to the selected profiles. Depending on the kind of documents to be expected, you can adjust the settings. For the segmentation result handling, you have two choices: either two separate profiles recognize the whole page or only one profile. When you select the option to only use a single profile, the Mixed print recognition method first checks the percentage amount of hand written text on the document and then decides whether the page is read by the machine print or the hand print profile. You can optimize the threshold by adjusting the percentage value with the slider.

If you choose a zone recognition profile for hand print recognition, the word separation characters have to be determined automatically. This is because the zone recognition profiles do not have word separation characters. The word separation characters are determined as follows:

  • If a machine print page profile is chosen, then its word separation characters are also used for the zone recognition.

  • If no profile is chosen for machine print then the default word separation characters ( /:()-# ) are applied.

The physical coordinates of the areas containing hand written text or signatures can be accessed via script. See the Detecting a Signature on a Document topic in the Scripting Help for more information.

You can add a Mixed Print page recognition profile by following these steps:

  1. On the Project tab, in the Configuration group, select Project Settings Project Settings icon.
  2. Select the Recognition tab to view the recognition settings.
  3. Click the Page Profile button. A properties window is displayed.
  4. Choose a Page Recognizer.

    The properties displayed on the window automatically update if you select a different recognizer.

  5. Edit the page recognition properties and click OK to save your settings and add the new profile.
  6. Optionally, rename the new profile so it has a descriptive name.
  7. Optionally, click OK to close the Project Settings window.
  8. Save the changes to your project.
