2023.1:Image Processing (Activity)

STUB	This article is a stub. It contains minimal information on the topic and should be expanded.

Image Processing is an Unattended Activity that performs three major functions in Grooper's workflow.

1. To apply archival image adjustments
2. To apply image cleanup operations in order to obtain better text data from OCR.
3. To obtain image-based data, including Layout Data (such as table line locations, barcode information, OMR checkbox states, and more) as well as image features used for Visual classification.

This is done by creating an IP Profile which lists a series of steps to perform individual image processing functions, called IP Commands.

Permanent vs. Temporary Image Processing

The Image Processing activity permanently alters a document's image by applying an IP Profile. However, it is possible to temporarily clean up document images and revert back to the original document image. This is done during the Recognize activity.

For example, you may have a document where table lines are getting in the way of accurate OCR. However, if you remove these lines during the Image Processing activity, they will be permanently removed, making it difficult to review the documents in Data Review and changing the archival image stored later to something that no longer looks like the original document.

Instead, you can use an OCR Profile referencing an IP Profile containing a Line Removal command during Recognize. The image will be temporarily changed according to the IP Profile. Then, OCR will run on the altered image. Last, the image will revert back to its original form.

• Furthermore, any image based data targeted by the IP Profile (such as the table line locations for this example) will still be saved to the Batch Page for later use.
