Detailed Description

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

Calculates the covariance matrix of the target sample data.

The filter calculates first the sample mean and use it in the covariance calculation. The covariance is computed as follows Let \(\Sigma\) denotes covariance matrix for the sample, then: When \(x_{i}\) is \(i\)th component of a measurement vector \(\vec x\), \(\mu_{i}\) is the \(i\)th component of the \(\vec\mu\), and the \(\sigma_{ij}\) is the \(ij\)th component \(\Sigma\), \(\sigma_{ij} = (x_{i} - \mu_{i})(x_{j} - \mu_{j})\)

Without the plugged in mean vector, this calculator will perform the single pass mean and covariance calculation algorithm.

◆ MakeOutput() [1/2]

template<typename TSample>

virtual DataObjectPointer itk::ProcessObject::MakeOutput ( const DataObjectIdentifierType & )

virtual

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().

Reimplemented from itk::ProcessObject.
