Detailed Description

template<typename TOutputImage, typename TGradientOutputImage = itk::Image< itk::CovariantVector < typename TOutputImage::ValueType, TOutputImage::ImageDimension >, TOutputImage::ImageDimension >>
class rtk::ADMMTotalVariationConeBeamReconstructionFilter< TOutputImage, TGradientOutputImage >

Implements the ADMM reconstruction with total variation regularization.

This filter implements a reconstruction method based on compressed sensing. The method attempts to find the f that minimizes || sqrt(D) (Rf -p) ||_2^2 + alpha * TV(f), with R the forward projection operator, p the measured projections, D the displaced detector weighting matrix, and TV the total variation. Details on the method and the calculations can be found on page 48 of

Mory, C. "Cardiac C-Arm Computed Tomography", PhD thesis, 2014. https://hal.inria.fr/tel-00985728/document

\( f_{k+1} \) is obtained by linear conjugate solving the following:

\[ ( R^T R + \beta \nabla^T \nabla ) f = R^T p + \beta \nabla^T ( g_k + d_k ) \]

\( g_{k+1} \) is obtained by soft thresholding:

\[ g_{k+1} = ST_{ \frac{\alpha}{2 \beta} } ( \nabla f_{k+1} - d_k ) \]

\( d_{k+1} \) is a simple subtraction:

\[ d_{k+1} = g_{k+1} - ( \nabla f_{k+1} - d_k) \]
