Detailed Description

template<typename TMeasurement = float, typename TFrequencyContainer = DenseFrequencyContainer2>
class itk::Statistics::Histogram< TMeasurement, TFrequencyContainer >

This class stores measurement vectors in the context of n-dimensional histogram.

Histogram represents an ND histogram. Histogram bins can be regularly or irregularly spaced. The storage for the histogram is managed via the FrequencyContainer specified by the template argument. The default frequency container is a DenseFrequencyContainer. A SparseFrequencyContainer can be used as an alternative.

Frequencies of a bin (SetFrequency(), IncreaseFrequency()) can be specified by measurement, index, or instance identifier.

Measurements can be queried by bin index or instance identifier. In this case, the measurement returned is the centroid of the histogram bin.

The Initialize() method is used to specify the number of bins for each dimension of the histogram. An overloaded version also allows for regularly spaced bins to defined. To define irregularly sized bins, use the SetBinMin()/SetBinMax() methods.

If you do not know the length of the measurement vector at compile time, you should use the VariableDimensionHistogram class, instead of the Histogram class.

If you know the length of the measurement vector at compile time, it can conveniently be obtained from MeasurementVectorTraits. For instance, instantiate a histogram as below:

* typedef Histogram< THistogramMeasurement, typename TFrequencyContainer > HistogramType;
*

template<typename TMeasurement = float, typename TFrequencyContainer = DenseFrequencyContainer2>
itk::Statistics::Histogram< TMeasurement, TFrequencyContainer >::itkLegacyMacro ( const IndexType &GetIndex(const MeasurementVectorType &measurement)  const)

Get the index of a measurement value from the histogram.

Deprecated:
Use GetIndex(const MeasurementVectorType & measurement, IndexType & index ) const instead.
template<typename TMeasurement = float, typename TFrequencyContainer = DenseFrequencyContainer2>
double itk::Statistics::Histogram< TMeasurement, TFrequencyContainer >::Mean ( unsigned int  dimension) const

Get the mean value for a dimension

Methods invoked by Print() to print information about the object including superclasses. Typically not called by the user (use Print() instead) but used in the hierarchical print process to combine the output of several classes.

Reimplemented from itk::Statistics::Sample< Array< TMeasurement > >.

template<typename TMeasurement = float, typename TFrequencyContainer = DenseFrequencyContainer2>
double itk::Statistics::Histogram< TMeasurement, TFrequencyContainer >::Quantile ( unsigned int  dimension,
double  p 
) const

Get the pth percentile value for a dimension.

Let assume n = the index of the bin where the p-th percentile value is,
min = min value of the dimension of the bin,
max = max value of the dimension of the bin,
interval = max - min ,
pp = cumlated proportion until n-1 bin;
and pb = frequency of the bin / total frequency of the dimension.

If p is less than 0.5,
the percentile value =
min + ((p - pp ) / pb) * interval
If p is greater than or equal to 0.5
the percentile value =
max - ((pp - p) / pb) * interval

Set to false to have the bins at edges of the histogram extend to +/- infinity.

template<typename TMeasurement = float, typename TFrequencyContainer = DenseFrequencyContainer2>
void itk::Statistics::Histogram< TMeasurement, TFrequencyContainer >::SetFrequency ( AbsoluteFrequencyType  value)

Set all the bins in the histogram to a specified frequency

bool itk::Statistics::Histogram< TMeasurement, TFrequencyContainer >::SetFrequency ( InstanceIdentifier  id,
AbsoluteFrequencyType  value

Set the frequency of an index. Returns false if the bin is out of bounds.

template<typename TMeasurement = float, typename TFrequencyContainer = DenseFrequencyContainer2>
bool itk::Statistics::Histogram< TMeasurement, TFrequencyContainer >::SetFrequencyOfMeasurement ( const MeasurementVectorType measurement,
AbsoluteFrequencyType  value

Set the frequency of a measurement. Returns false if the bin is out of bounds.

template<typename TMeasurement = float, typename TFrequencyContainer = DenseFrequencyContainer2>
void itk::Statistics::Histogram< TMeasurement, TFrequencyContainer >::SetToZero ( )

Initialize the values of the histogram bins to zero

template<typename TMeasurement = float, typename TFrequencyContainer = DenseFrequencyContainer2>
