A Signature Detection Data Field Zone is configured using the options on the Signature Detection Field tab of the Data Field Zone dialog box.
Data Field Zone Signature Detection Field Options |
Description |
---|---|
Keyword type |
Using this drop-down list, select the Keyword Type that this Data Field Zone will assign a Keyword Value to. If the currently-displayed Advanced Capture form has an assigned Document Type, only the Keyword Types associated with the assigned Document Type are available in the drop-down list. If no Document Type is assigned to the currently-displayed Advanced Capture form, only the <None> option is available in the drop-down list. Note:
If the Keyword Value identified by the OCR engine exceeds the maximum length of the Keyword Type it is assigned to, then the Keyword Value is truncated to fit this length. |
XML Node |
Note:
This field is only displayed if the Advanced Capture form is configured to create an XML rendition of documents matched to it (i.e., the Create XML data rendition option is selected for the Advanced Capture form). Enter the name of the XML node (i.e., the element) that Keyword Values extracted from this zone are contained in when the XML rendition of the document is created. Note:
While the XML Node (Parent) name may include alphanumeric characters, underscores (_), hyphens (-), or periods (.), it must begin with either a letter or an underscore. |
Keyword Values |
In the Positive Result Value field, enter the Keyword Value that is assigned if the OCR engine determines that a signature is present. In the Negative Result Value field, enter the Keyword Value that is assigned if the OCR engine determines that a signature is not present. For example: you are processing an application that requires a signature to indicate that the data has been verified. Depending on if a signature is present or not, a Keyword Value is assigned to the Verified Keyword Type.

Page Location(s) |
The Page Location(s) options control the pages that the OCR engine searches for a particular Data Field Zone.
|
Options |
Select the radio button that describes the signature being read by the OCR engine.
To ignore machine-printed text in the Data Field Zone (e.g., Signature, Applicant Signature, etc.), select the Exclude machine print text check box. This prevents the signature detection results from being impacted by the presence of machine-printed text. |
Sensitivity |
Select a radio button to determine the Suspect Level for this Data Field Zone.
The Suspect Level is the level of confidence placed in the processing results for this field. After a zone is processed, the OCR engine gives the resulting value a score between 1 and 99, depending on how confident it is in the result that was returned. The higher the score is, the lower the OCR engine's confidence is in the results. The Sensitivity level selected for this field is the threshold at which the OCR engine determines if a returned value is acceptable or suspect. A score returned by the OCR engine higher than the Suspect Level threshold you set causes the value captured from the zone to be marked as suspect. All scores lower than the Suspect Level threshold indicate that the captured value is considered by the OCR engine to be acceptable. For example, setting the Sensitivity to Lowest would indicate you have a fair amount of confidence in the result returned by the OCR engine because few higher scores could be returned and fewer results would be determined to be suspect. Setting the Suspect Level to Highest would indicate you have less confidence in the result because a great number of lower scores could be returned and more results would be determined as suspect. |
Advanced filtering |
Use the VB script drop-down to select a VB script to associate with the processing of this Data Field Zone. Click the ... button to open the VB Scripts dialog box. Here, the selected script can be re-configured or edited. |
Test |
Click the Test button to have the OCR engine perform a test process on the Data Field Zone and attempt to detect a signature using the options you have specified. If the Advanced Capture engine is configured to attempt to compensate for offset data, the resulting offset/scaling adjustments will take place during the test. Once the test process is complete, a dialog box is displayed indicating if a signature was detected and the Keyword Value that would be assigned based on this result. The offset/scaling information is also displayed in the dialog box. |
Keyword association |
You can logically group Data Field Zones using Keyword association. These groupings can be used to identify Keywords that belong to a Multi-Instance Keyword Type Group. Use the Keyword association field to enter or select a logical group name for the Data Field Zones that identify Keywords belonging to an MIKG. The Advanced Capture engine will attempt to maintain this Keyword grouping on the resulting document. |
Colors |
If you would like to assign specific colors to the Keyword Type configured for the Data Field Zone, click the Colors button. The Display Colors dialog box is displayed. Here you can change the colors in which any regular or suspect values for the corresponding Keyword Type are displayed in the Indexing panel once Advanced Capture processing has taken place.
Note:
Any colors assigned here can be overridden by colors assigned through Keyword Lookup/Replace settings and/or VB scripting. |
Activation groups |
When you have configured multiple Form Identification Zones or Page Registration Zones for a document, you can assign individual Data Field Zones to a specific Form Identification or Page Registration Zone using activation groups. Activation groups allow you to activate only the Data Field Zones assigned to the Form Identification or Page Registration Zone that is used to match the document to an Advanced Capture form. Data Field Zones assigned to Form Identification or Page Registration Zones that are not used to match the document to a form will not be processed. Also, Data Field Zones present on pages other than the pages containing their assigned Form Identification or Page Registration Zones will not be processed, unless otherwise specified through the Page Location(s) setting or by adding a + to the front of the activation group name on the Form Identification or Page Registration Zone. This selective activation saves processing time and reduces the number of forms that need to be created for a Document Type. Use the Activation groups field to enter or select an activation group name. Add a + to the front of a group name (e.g., +Group1) on a Form Identification or Page Registration Zone to set all Data Field Zones assigned to this group to be processed. Use commas to separate multiple group names.
|
Activation groups (cont.) |
Alternatively, you can assign a form definition group as the Data Field Zone's activation group to activate the zone for processing. Form definition groups can be used to extract only specific types of information (e.g., header data vs. detail data) during processing. In the Activation groups drop-down list, form definition groups are enclosed in brackets (e.g., [Group1]). |
