Detailed Description

template<class TInputImage>
class itk::TobogganImageFilter< TInputImage >

toboggan image segmentation The Toboggan segmentation takes a gradient magnitude image as input and produces an (over-)segmentation of the image based on connecting each pixel to a local minimum of gradient. It is roughly equivalent to a watershed segmentation of the lowest level.

The output is a 4 connected labeled map of the image.

Member Function Documentation

template<class TInputImage>
void itk::TobogganImageFilter< TInputImage >::EnlargeOutputRequestedRegion (  DataObject *   )  [virtual]
 

Give the process object a chance to indictate that it will produce more output than it was requested to produce. For example, many imaging filters must compute the entire output at once or can only produce output in complete slices. Such filters cannot handle smaller requested regions. These filters must provide an implementation of this method, setting the output requested region to the size they will produce. By default, a process object does not modify the size of the output requested region.

Reimplemented from itk::ProcessObject.

template<class TInputImage>
void itk::TobogganImageFilter< TInputImage >::GenerateData (   )  [virtual]
 

Standard process object method. This filter is not multithreaded.

Reimplemented from itk::ImageSource< TOutputImage >.

template<class TInputImage>
void itk::TobogganImageFilter< TInputImage >::GenerateInputRequestedRegion (   )  [virtual]
 

What is the input requested region that is required to produce the output requested region? The base assumption for image processing filters is that the input requested region can be set to match the output requested region. If a filter requires more input (for instance a filter that uses neighborhoods needs more input than output to avoid introducing artificial boundary conditions) or less input (for instance a magnify filter) will have to override this method. In doing so, it should call its superclass' implementation as its first step. Note that imaging filters operate differently than the classes to this point in the class hierachy. Up till now, the base assumption has been that the largest possible region will be requested of the input.

This implementation of GenerateInputRequestedRegion() only processes the inputs that are a subclass of the ImageBase<InputImageDimension>. If an input is another type of DataObject (including an Image of a different dimension), they are skipped by this method. The subclasses of ImageToImageFilter are responsible for providing an implementation of GenerateInputRequestedRegion() when there are multiple inputs of different types.
