I am trying to implement Despeckle functionality for our company scan module, and I don't know which class to use -- DespeckleCommand or DotRemoveCommand?

Can you explain what the difference is between these classes, and when to use what classes? Our scan module, depending on the scanner, can take either B&W, grayscale or color images.

Thank you,

These two functions work only on Black and White images. They are part of LEADTOOLS Document Imaging toolkit Clean-up functions.

There are differences between these two functions, the main difference is that the DotRemoveCommand class can control the size of the "dots" on your image to remover. However, the DespeckleCommand class will remove very small speckles in the scanned image and smooth it.

For better understanding to the effect these two classes have on the images, please run the LEADTOOLS Document Clean-up demo shipped with our toolkit. You can find a shortcut for this demo in this folder:
[LEADTOOLS 16.5 folder]\Shortcuts\.NET Class Library\02 Document\02 Clean-Up App.

The links below are for the .NET help pages for these two classes:
