#include <itkMahalanobisDistanceThresholdImageFunction.h>
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 specified 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.
