Detailed Description

template<class TGradient, class THessian = itk::Image<itk::Vector<typename TGradient::PixelType::ValueType, TGradient::PixelType::Dimension * TGradient::PixelType::Dimension>, TGradient::ImageDimension>>
class rtk::GetNewtonUpdateImageFilter< TGradient, THessian >

Computes update from gradient and Hessian in Newton's method.

This filter takes in inputs the gradient G (input 1) and the Hessian H (input 2) of a cost function, and computes the update U (output), by U = H^{-1} * G. In Newton's method, the quantity to add to the current iterate in order to get the next iterate is actually -U, so the minus operation has to be handled downstream. It is assumed that the cost function is separable, so that each pixel can be processed independently and has its own small G, H and U
