Detailed Description

template<class 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 componet of the $\vec\mu$, and the $\sigma_{ij}$ is the $ij$th componet $\Sigma$, $\sigma_{ij} = (x_{i} - \mu_{i})(x_{j} - \mu_{j})$

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

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().
