Advanced Despeckle

This cleanup method removes unwanted blobs from an image. A blob is a group of connected pixels that are part of an image background or stray marks, that are not removed by scanning.

You can layer more than one Advanced Despeckle on top of another to remove items of different sizes from an image. For example, you can remove repeating patterns or target specific boxes for removal.

You can also use this cleanup method to recognize the presence of hand written mark-up, remove boxes, repeating patterns, images, and other graphics from documents. Once these items are removed from the document, recognition rates can be significantly improved.

When configuring this image cleanup method, test a range of documents to ensure that you are not removing important text or data needed for extraction.
