Detailed Description

template<typename TImage>
class rtk::NesterovUpdateImageFilter< TImage >

Applies Nesterov's momentum technique.

NesterovUpdateImageFilter implements Nesterov's momentum technique in order to accelerate the convergence rate of Newton's method, or other optimization algorithms. The implementation is based on the description of [Mechlem et al, 10.1109/TMI.2017.2726687, 2018], based on [Kim et al, 10.1109/TMI.2014.2350962, 2015] implementing [Nesterov, 10.1007/s10107-004-0552-5, 2005] for ordered-subset tomographic reconstruction. The first input is the current iterate, the second input is the opposite of the next step, e.g., the product of the inverse hessian matrix by the gradient vector for an update of Newton's algorithm before applying a minus sign.
