Image Processing

Code Activity Grooper.Activities

Applies permanent image cleanup to images in a Batch.

Remarks

This activity executes an IP Profile against the image content of each Batch Page or Batch Folder in scope, replacing the original image with the results of image processing.

Overview

  • Primarily used to apply permanent image cleanup to image-based pages.
  • Should be run before Recognize so that any rotations or skew corrections are reflected in character coordinates.
  • Typically runs after Review (for scanned documents) or Split Pages (for imported documents).
  • Executes the selected IP Profile on each image, applying a sequence of IP Commands such as deskew, despeckle, or orientation correction.

Page-Level Processing

  • If the page is image-based, the IP Profile is executed on the primary image. If changes are made, the page's primary image is replaced.
  • For PDF-based pages, the Bursting and Rendering properties control how the page is processed:
    • By default, image-based PDF pages are handled like images, while text/vector PDF pages are left unaltered (except for orientation).
    • See the property documentation for configuration details.

Folder-Level Processing

  • Should only be executed at the folder level for small image-based attachments (10 pages or less).
  • When run on a folder, all pages of the attached image file are processed. If changes are made, the attachment is replaced with a multi-page TIFF.
  • For best performance and parallelism, split documents to individual pages before running this activity.

Usage Scenarios

  • Permanent Cleanup: Remove noise, correct skew, or apply other cleanup before OCR or export.
  • PDF Handling: Normalize orientation or extract images from PDF-based pages.
  • Undo Support: Optionally save undo images to allow reverting to the original state.
  • Batch Processing: Integrate as a step in a Batch Process for automated, repeatable image cleanup.

Configuration Tips

  • Select an IP Profile that matches your cleanup requirements.
  • Use EnableUndo to allow reverting changes if needed.
  • Adjust Bursting and Rendering for PDF handling based on your document types.
  • For large documents, split to pages for optimal performance.

Related Concepts

  • IP Profile: Defines the sequence of image processing commands.
  • IP Command: Individual image processing operations (e.g., deskew, despeckle).
  • Batch Page, Batch Folder: The objects being processed.
  • Recognize: Downstream OCR activity that benefits from cleaned images.
