Detailed Description

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

Implements the operator A used in the conjugate gradient step of ADMM reconstruction with total variation regularization.

This filter implements the operator A used in the conjugate gradient step of 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 in

Mory, C., B. Zhang, V. Auvray, M. Grass, D. Schafer, F. Peyrin, S. Rit, P. Douek, and L. Boussel. "ECG-Gated C-Arm Computed Tomography Using L1 Regularization." In Proceedings of the 20th European Signal Processing Conference (EUSIPCO), 2728-32, 2012.

This filter takes in input f and outputs R_t D R f - beta div(grad(f)).
