Detailed Description

template<typename TOutputImage, typename TSingleComponentImage = TOutputImage, typename TWeightsImage = TOutputImage>
class rtk::ReconstructionConjugateGradientOperator< TOutputImage, TSingleComponentImage, TWeightsImage >

Implements the operator A used in conjugate gradient reconstruction.

This filter implements the operator A used in the conjugate gradient reconstruction method, which attempts to find the f that minimizes || sqrt(D) (Rf -p) ||_2^2 + gamma || grad f ||_2^2 + Tikhonov || f ||_2^2, with R the forward projection operator, p the measured projections, and D the displaced detector weighting operator.

With gamma=0, this it is similar to the ART and SART methods. The difference lies in the algorithm employed to minimize this cost function. ART uses the Kaczmarz method (projects and back projects one ray at a time), SART the block-Kaczmarz method (projects and back projects one projection at a time), and ConjugateGradient a conjugate gradient method (projects and back projects all projections together).

This filter takes in input f and outputs R_t D R f + gamma Laplacian f + Tikhonov f
