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.

Examples:
Examples/Statistics/SampleStatistics.cxx.

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().
