class itk::ANTSNeighborhoodCorrelationImageToImageMetricv4< TFixedImage, TMovingImage, TVirtualImage, TInternalComputationValueType, TMetricTraits >

Computes normalized cross correlation using a small neighborhood for each voxel between two images, with speed optimizations for dense registration.

Please cite this reference for more details:

Brian B. Avants, Nicholas J. Tustison, Gang Song, Philip A. Cook, Arno Klein, James C. Gee, A reproducible evaluation of ANTs similarity metric performance in brain image registration, NeuroImage, Volume 54, Issue 3, 1 February 2011, Pages 2033-2044, ISSN 1053-8119, DOI: 10.1016/j.neuroimage.2010.09.025.

Around each voxel, the neighborhood is defined as a N-Dimensional rectangle centered at the voxel. The size of the rectangle is 2*radius+1. The normalized correlation between neighborhoods of fixed image and moving image are averaged over the whole image as the final metric.

Note: A radius less than 2 can be unstable. 2 is the default.

This class uses a specific fast implementation that is described in the above paper. There are two particular speed-ups:

1) It is assumed that the derivative is only affected by changes in the transform at the center of the window. This is obviously not true but speeds the evaluation up considerably and works well in practice. This assumption is the main differentiation of this approach from a more generic one.

2) The evaluation uses on-the-fly queues with multi-threading and a sliding neighborhood window. This is described in the above paper and specifically optimized for dense registration.

Example of usage:

using MetricType = itk::ANTSNeighborhoodCorrelationImageToImageMetricv4 <ImageType, ImageType>; using MetricTypePointer = MetricType::Pointer; MetricTypePointer metric = MetricType::New();

// set all parameters Size<Dimension> neighborhoodRadius; neighborhoodRadius.Fill(2); metric->SetRadius(neighborhood_radius); metric->SetFixedImage(fixedImage); metric->SetMovingImage(movingImage); metric->SetFixedTransform(transformFix); metric->SetMovingTransform(transformMov);

// initialization after parameters are set. metric->Initialize();

// getting derivative and metric value metric->GetValueAndDerivative(valueReturn, derivativeReturn);

This class is templated over the type of the two input objects. This is the base class for a hierarchy of similarity metrics that may, in derived classes, operate on meshes, images, etc. This class computes a value that measures the similarity between the two objects.
