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 the mean an covariance to be used. 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.
