Detailed Description

template<class TInputImage, class TCoordRep = float>
class itk::MahalanobisDistanceThresholdImageFunction< TInputImage, TCoordRep >

Returns true if the pixel value of a vector image has a Mahalanobis distance below the value specified by the threshold.

This ImageFunction returns true if the pixel value of a vector image has a Mahalanobis distance below the value specided by the threshold. The Mahalanobis distance is computed with the MahalanobisDistanceMembershipFunction class which has to be initialized with a mean and covariance. This class is intended to be used only with images whose pixel type is a vector (array).

The input image is set via method SetInputImage().

Methods Evaluate, EvaluateAtIndex and EvaluateAtContinuousIndex respectively evaluate the function at an geometric point, image index and continuous image index.

Member Function Documentation

template<class TInputImage , class TCoordRep = float>
virtual::itk::LightObject::Pointer itk::MahalanobisDistanceThresholdImageFunction< TInputImage, TCoordRep >::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 TCoordRep = float>
virtual bool itk::MahalanobisDistanceThresholdImageFunction< TInputImage, TCoordRep >::Evaluate ( const PointType &  point) const [virtual]

BinaryThreshold the image at a point position

Returns true if the image intensity at the specified point position satisfies the threshold criteria. The point is assumed to lie within the image buffer.

ImageFunction::IsInsideBuffer() can be used to check bounds before calling the method.
