How To Migrate your code to the New Statistics Framework

Measurement Containers



Class Name Fate New Use
KdTree Refactored
Histogram Refactored
VariableDimensionHistogram
ListSampleBase Deprecated The class was unecessary, it was providing only a Search() method that should in fact be provided by a process class, not a data container. If you were deriving from this class, you should now derive directly from the itk::Sample. If you were using the Search() method you can get that functionality now from the itkStatisticsAlgorithm Search() algorithm.
ListSample Refactored The iterators API was updated, const-correctness is now enforced
Sample Refactored const-correctness is now enforced. It now derives from DataObject
Subsample Refactored The concept of Indices and InstanceIdentifiers was fixed. InstanceIdentifiers were previously referring to the original Sample, they are now referring to the current Subsample set of measurement vectors. The basic principle followed now in the design of the Subsample class is that the subsample should behave as a sample. That is, a user should be able to use a Subsample class in any algorithm that is expecting a Sample.
MembershipSample Refactored It does not derive from itk::Sample anymore, instead it derives from DataObject.

Frequency Containers

Process Objects

Calculators

Class Name Fate New Use
CovarianceCalculator Refactored Now called Covariance Filter.... new API : GetOutput(), SetInput(), GetMean().... removed API : SetMean() because it was inconsistant
GreyLevelCooccurrenceMatrixTextureCoefficientsCalculator Refactored (now HistogramToTextureFeaturesFilter : ProcessObject)...
MeanCalculator Refactored (now MeanFilter : ProcessObject)...
ScalarImageTextureCalculator Refactored now called.... Filter ?
WeightedCovarianceCalculator Refactored now WeightedCovarianceFilter.... describe API changes
WeightedMeanCalculator Refactored now WeightedMeanFilter ... describe API changes
