Detailed Description

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

Suppress local minima whose depth below the baseline is less than h.

HMinimaImageFilter suppresses local minima that are less than h intensity units below the (local) background. This has the effect of smoothing over the "low" parts of the noise in the image without smoothing over large changes in intensity (region boundaries). See the HMaximaImageFilter to suppress the local maxima whose height is less than h intensity units above the (local) background.

If original image is subtracted from the output of HMinimaImageFilter, the signicant "valleys" in the image can be identified. This is what the HConcaveImageFilter provides.

This filter uses the GrayscaleGeodesicErodeImageFilter. It provides its own input as the "mask" input to the geodesic dilation. The "marker" image for the geodesic dilation is the input image plus the height parameter h.

Geodesic morphology and the H-Minima algorithm is described in Chapter 6 of Pierre Soille's book "Morphological Image Analysis: Principles and Applications", Second Edition, Springer, 2003.

Member Function Documentation

template<class TInputImage , class TOutputImage >
virtual::itk::LightObject::Pointer itk::HMinimaImageFilter< TInputImage, TOutputImage >::CreateAnother ( void  ) const [virtual]

Create an object from an instance, potentially deferring to a factory. This method allows you to create an instance of an object that is exactly the same type as the referring object. This is useful in cases where an object has been cast back to a base class.

Reimplemented from itk::Object.

template<class TInputImage , class TOutputImage >
void itk::HMinimaImageFilter< TInputImage, TOutputImage >::EnlargeOutputRequestedRegion ( DataObject ) [protected, virtual]

HMinimaImageFilter will produce the entire output.

Reimplemented from itk::ProcessObject.

template<class TInputImage , class TOutputImage >
virtual void itk::HMinimaImageFilter< TInputImage, TOutputImage >::FullyConnectedOff ( ) [virtual]

Set/Get whether the connected components are defined strictly by face connectivity or by face+edge+vertex connectivity. Default is FullyConnectedOff. For objects that are 1 pixel wide, use FullyConnectedOn.

template<class TInputImage , class TOutputImage >
virtual void itk::HMinimaImageFilter< TInputImage, TOutputImage >::FullyConnectedOn ( ) [virtual]

Set/Get whether the connected components are defined strictly by face connectivity or by face+edge+vertex connectivity. Default is FullyConnectedOff. For objects that are 1 pixel wide, use FullyConnectedOn.

template<class TInputImage , class TOutputImage >
void itk::HMinimaImageFilter< TInputImage, TOutputImage >::GenerateData ( ) [protected, virtual]

Single-threaded version of GenerateData. This filter delegates to GrayscaleGeodesicErodeImageFilter.

Reimplemented from itk::ImageSource< TOutputImage >.

template<class TInputImage , class TOutputImage >
void itk::HMinimaImageFilter< TInputImage, TOutputImage >::GenerateInputRequestedRegion ( ) [protected, virtual]

HMinimaImageFilter needs the entire input be available. Thus, it needs to provide an implementation of GenerateInputRequestedRegion().

Reimplemented from itk::ImageToImageFilter< TInputImage, TOutputImage >.

template<class TInputImage , class TOutputImage >
virtual const bool& itk::HMinimaImageFilter< TInputImage, TOutputImage >::GetFullyConnected ( ) [virtual]

Set/Get whether the connected components are defined strictly by face connectivity or by face+edge+vertex connectivity. Default is FullyConnectedOff. For objects that are 1 pixel wide, use FullyConnectedOn.

template<class TInputImage , class TOutputImage >
virtual InputImagePixelType itk::HMinimaImageFilter< TInputImage, TOutputImage >::GetHeight ( ) const [virtual]

Set/Get the height that a local maximum must be above the local background (local contrast) in order to survive the processing. Local maxima below this value are replaced with an estimate of the local background.

template<class TInputImage , class TOutputImage >
virtual const char* itk::HMinimaImageFilter< TInputImage, TOutputImage >::GetNameOfClass ( ) const [virtual]

Runtime information support.

Reimplemented from itk::ImageToImageFilter< TInputImage, TOutputImage >.

template<class TInputImage , class TOutputImage >
static Pointer itk::HMinimaImageFilter< TInputImage, TOutputImage >::New ( ) [static]

Standard New method.

Reimplemented from itk::Object.

template<class TInputImage , class TOutputImage >
void itk::HMinimaImageFilter< TInputImage, TOutputImage >::operator= ( const Self ) [private]

PushBackInput(), PushFronInput() in the public section force the input to be the type expected by an ImageToImageFilter. However, these methods end of "hiding" the versions from the superclass (ProcessObject) whose arguments are DataObjects. Here, we re-expose the versions from ProcessObject to avoid warnings about hiding methods from the superclass.

Reimplemented from itk::ImageToImageFilter< TInputImage, TOutputImage >.
