How it works...

The ImageRegistrationMethod class provides an interface method to the modular SimpleITK (v4) registration framework. This class captures all of the necessary elements required to execute a simple image registration between two images.

Registration will done using optimization; the SetOptimizerAsGradientDescent() method implements a simple gradient descent optimizer. At each iteration, the current parameter is updated according to the following equation (where f is the objective function for the optimization and p_n represents the value of a parameter, p, at iteration n, with a parameter that can be initialized with a small random value):

The parameters passed to the gradient descent function are learningRate (defaults to ...
