Detailed Description

class itk::MattesMutualInformationImageToImageMetricv4< TFixedImage, TMovingImage, TVirtualImage, TInternalComputationValueType, TMetricTraits >

Computes the mutual information between two images to be registered using the method of Mattes et al.

MattesMutualInformationImageToImageMetric computes the mutual information between a fixed and moving image to be registered.

This class is templated over the FixedImage type and the MovingImage type.

The calculations are based on the method of Mattes et al [1,2] where the probability density distribution are estimated using Parzen histograms. Since the fixed image PDF does not contribute to the derivatives, it does not need to be smooth. Hence, a zero order (box car) BSpline kernel is used for the fixed image intensity PDF. On the other hand, to ensure smoothness a third order BSpline kernel is used for the moving image intensity PDF.

During each call of GetValue(), GetDerivatives(), GetValueAndDerivatives(), marginal and joint intensity PDF's values are estimated at discrete position or bins. The number of bins used can be set via SetNumberOfHistogramBins(). To handle data with arbitray magnitude and dynamic range, the image intensity is scale such that any contribution to the histogram will fall into a valid bin.

One the PDF's have been contructed, the mutual information is obtained by doubling summing over the discrete PDF values.

Warning: Local-support transforms are not yet supported. If used, an exception is thrown during Initialize().

Note: The per-iteration post-processing code is not multi-threaded, but could be readily be made so for a small performance gain. See GetValueCommonAfterThreadedExecution(), GetValueAndDerivative() and threader::AfterThreadedExecution().

The algorithm and much of the code was copied from the previous Mattes MI metric, i.e. itkMattesMutualInformationImageToImageMetric.

See MattesMutualInformationImageToImageMetricv4GetValueAndDerivativeThreader::ProcessPoint for poritons of the algorithm implementation.

See ImageToImageMetricv4 for details of common metric operation and options.
