#include <itkImageToImageMetric.h>
Computes similarity between regions of two images.
This Class is templated over the type of the two input images. It expects a Transform and an Interpolator to be plugged in. This particular class is the base class for a hierarchy of similarity metrics.
This class computes a value that measures the similarity between the Fixed image and the transformed Moving image. The Interpolator is used to compute intensity values on non-grid positions resulting from mapping points through the Transform.

This boolean flag is only relevant when this metric is used along with a BSplineBaseTransform. The flag enables/disables the caching of values computed when a physical point is mapped through the BSplineBaseTransform. In particular it will cache the values of the BSpline weights for that points, and the indexes indicating what BSpline-grid nodes are relevant for that specific point. This caching is made optional due to the fact that the memory arrays used for the caching can reach large sizes even for moderate image size problems. For example, for a 3D image of 256^3, using 20% of pixels, these arrays will take about 1 Gigabyte of RAM for storage. The ratio of computing time between using the cache or not using the cache can reach 1:5, meaning that using the caching can provide a five times speed up. It is therefore, interesting to enable the caching, if enough memory is available for it. The caching is enabled by default, in order to preserve backward compatibility with previous versions of ITK.

void itk::ImageToImageMetric< TFixedImage, TMovingImage >::ReinitializeSeed | ( | ) |
Reinitialize the seed of the random number generator that selects the sample of pixels used for estimating the image histograms and the joint histogram. By nature, this metric is not deterministic, since at each run it may select a different set of pixels. By initializing the random number generator seed to the same value you can restore determinism. On the other hand, calling the method ReinitializeSeed() without arguments will use the clock from your machine in order to have a very random initialization of the seed. This will indeed increase the non-deterministic behavior of the metric.

Types and variables related to BSpline deformable transforms. If the transform is of type third order BSplineBaseTransform, then we can speed up the metric derivative calculation by only inspecting the parameters within the support region of a mapped point.
The number of BSpline transform weights is the number of of parameter in the support region (per dimension ).
