#include <itkMeanSampleFilter.h>

Detailed Description

template<typename TSample>
class itk::Statistics::MeanSampleFilter< TSample >

Given a sample, this filter computes the sample mean.

The sample is plugged in using SetSample method. Then invoke update() method to compute the sample mean.

The sample mean is computed as follows \( = \frac{1}{n}\sum^{n}_{i=1}x_{i}\) where \(n\) is the number of measurement vectors in the target

Recent API changes: The static const macro to get the length of a measurement vector, 'MeasurementVectorSize' has been removed to allow the length of a measurement vector to be specified at run time. It is now obtained from the input sample. Please use the function GetMeasurementVectorSize() to obtain the length.

overrideprotectedvirtual

Make a DataObject of the correct type to used as the specified output.

Every ProcessObject subclass must be able to create a DataObject that can be used as a specified output. This method is automatically called when DataObject::DisconnectPipeline() is called. DataObject::DisconnectPipeline, disconnects a data object from being an output of its current source. When the data object is disconnected, the ProcessObject needs to construct a replacement output data object so that the ProcessObject is in a valid state. So DataObject::DisconnectPipeline eventually calls ProcessObject::MakeOutput. Note that MakeOutput always returns a itkSmartPointer to a DataObject. ImageSource and MeshSource override this method to create the correct type of image and mesh respectively. If a filter has multiple outputs of different types, then that filter must provide an implementation of MakeOutput().
