Detailed Description

A distance transform that stores distances to a 3D binary mask given as slices.

This class implements a 3D distance transform that makes it possible to evaluate the distance of each point in a 3D volume to a binary mask that is given by a set of 2D binary images that are interpreted like a 3D volume. It implements the Techical Report Pedro F. Felzenszwalb and Daniel P. Huttenlocher Distance Transforms of Sampled Functions Cornell Computing and Information Science TR2004-1963
