Run Image Analysis on Specific Documents

To run image analysis on specific documents, run the ImageServerAnalysis task. This task only processes documents that have the AUTN_NEEDS_IMAGE_SERVER_ANALYSIS document field, so you must add this field to any document that you want to process.

If you run analysis on a document that does not represent an image (or does not represent an image in a supported format), the task fails. CFS writes an error message to the field ImportErrorDescription, and indexes the document. For information about the image formats supported by Image Server, refer to the Image Server Administration Guide.

The following example shows how to configure the ImageServerAnalysis task.

[ImportTasks]
Post0=Lua:EnableImageAnalysis.lua
Post1=ImageServerAnalysis:ImageServerSettings

[ImageServerSettings]
ImageServerHost=server:18000,server2:18000
ImageAnalysisTaskSections=dococrtask,facerectask,objecttask
ImageAnalysisTransform=xslt/My_ImageAnalysis_Transform.xsl

The Post0 import task runs a Lua script that determines whether a file is suitable for image analysis. Your script must add the field AUTN_NEEDS_IMAGE_SERVER_ANALYSIS to any documents that are identified. For an example script that adds a field to a document, see Add a Field to a Document.

The Post1 import task is the ImageServerAnalysis task. It specifies the name of a section in the configuration file that contains the settings for the task. For information about the parameters that you can use to configure this task, refer to the Connector Framework Server Reference.
