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.
