Detailed Description

template<typename TOutputImage, typename TGradientImage = itk::Image<itk::CovariantVector<typename TOutputImage::ValueType, TOutputImage::ImageDimension - 1>, TOutputImage::ImageDimension>>
class rtk::TotalNuclearVariationDenoisingBPDQImageFilter< TOutputImage, TGradientImage >

Performs total nuclear variation denoising.

This filter implements "Joint reconstruction of multi-channel, spectral CT data via constrained total nuclear variation minimization", by Rigie & LaRiviere, in Physics in Medicine and Biology 2015.

It uses basis pursuit dequantization, and is (mathematically) only a generalization of the TotalVariationDenoisingBPDQImageFilter to process multiple channel images. It outputs a multiple channel image close to the input one, for which the spatial gradient of each channel is sparser, and the gradient vectors are more similar (ie. colinear) across channels, than in the input.

The order of the channels is not taken into account, which makes this regularization more suitable when the channels describe materials (i.e. in spectral CT) or colors (i.e. in RGB images) than when they describe time frames (i.e. in dynamic CT).
