/** \class ImageToPathFilter
* \brief Base class for filters that take an image as input and produce an path as output.
*
* ImageToPathFilter is the base class for all process objects that output
* path data and require image data as input. Specifically, this class
* defines the SetInput() method for defining the input to a filter.
*

* "ContourExtractor2DImageFilter: A subpixel-precision image isocontour extraction filter."
