Detailed Description

Class for thresholding operations.

Essentially there are two different types of Threshold functions:

non-"Val" functions will cut pixel intensities above or below a given threshold by setting the result pixels to the threshold value itself.
"Val" functions will set all pixels outside the allowed intensity range to a specific given value.

Functions flavours

There exist two different types off function interfaces:

First, functions working on ImgBase base classes, which can deal with arbitrary depths of the actual images. After ensuring the correct depth and size of the destination image, these functions delegate the call to an appropriate type-specific function depending on the source images type.
Second, overloaded specializations working directly on a specific Img<T> type.
