itk::ParzenWindowMutualInformationImageToImageMetric< TFixedImage, TMovingImage > Class Template Reference

#include <itkParzenWindowMutualInformationImageToImageMetric.h>

Detailed Description

template<class TFixedImage, class TMovingImage>
class itk::ParzenWindowMutualInformationImageToImageMetric< TFixedImage, TMovingImage >

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

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

The calculations are based on the method of Mattes et al. [1,2], where the probability density distribution are estimated using Parzen histograms. Once the PDFs have been constructed, the mutual information is obtained by double summing over the discrete PDF values.

Construction of the PDFs is implemented in the superclass ParzenWindowHistogramImageToImageMetric.

This implementation of the MattesMutualInformation is based on the AdvancedImageToImageMetric, which means that:

• It uses the ImageSampler-framework
• It makes use of the compact support of B-splines, in case of B-spline transforms.
• Image derivatives are computed using either the B-spline interpolator implementation or by nearest neighbor interpolation of a precomputed central difference image.
• A minimum number of samples that should map within the moving image (mask) can be specified.

Notes:

1. This class returns the negative mutual information value.
   
2. This class in not thread safe due the private data structures used to the store the marginal and joint pdfs.

Get the value and analytic derivative. Called by GetValueAndDerivative if UseFiniteDifferenceDerivative == false.

Implements a version that only loops once over the samples, but uses a large block of memory to explicitly store the joint histogram derivative. It's size is #FixedHistogramBins * #MovingHistogramBins * #parameters * float.

Get the value and analytic derivative. Called by GetValueAndDerivative if UseFiniteDifferenceDerivative == false and UseExplicitPDFDerivatives == false.

Implements a version that avoids the large memory allocation of the explicit joint histogram derivative. This comes at the cost of looping over the samples twice, instead of once. The first time does not require GetJacobian() and moving image derivatives, however.
