Detailed Description

template<class TInputImage, class TOutputImage>
class itk::LevelTracingImageFilter< TInputImage, TOutputImage >

Trace a level curve/surface given a seed point on the level curve/surface.

LevelTracingImageFilter traces a level curve (or surface) from a seed point. The pixels on this level curve "boundary" are labeled as 1. Does nothing if seed is in uniform area.

LevelTracingImageFilter provides a quick method to select a point on a boundary of an object in a grayscale image and retrieve the entire boundary of the object.

For 2D images, the algorithm follows the boundary using 8-connected neighbors. For ND images, the algorithm traces the boundary using face connected neighbors.
