Detailed Description

ImageFunctions are typically used as helper classes in the implementation of ITK filters. In many cases they may act as pluggable components at run time, while in other cases they may be implementing the actions that a filter will apply at every iteration, or the operation a filter may apply to every pixel. These classes are rarely used from applications. Their main role is to assist in the implementation of ITK filters.
