 ## Overview
 
 This is a module for the Insight Toolkit ([ITK](https://github.com/InsightSoftwareConsortium/ITK)) that provides functionality to discard pixels within a masked region. Unlike masking, the pixels in the masked region are replaced (dissolved) by their nearest pixels outside the mask. This can be useful to clean-up label fields, e.g. to remove small islands/holes or remove entire labels, and replace them by the adjacent labels.
