Detailed Description

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

Computes the normalized mutual information between two images to be registered using a method based on Thevenaz&Unser [3].

ParzenWindowNormalizedMutualInformationImageToImageMetric computes the normalized mutual information between a fixed and moving image to be registered. The calculations are based on the method of Mattes et al [1,2] and Thevenaz&Unser [3], where the probability density distribution are estimated using Parzen histograms. The expression for the derivative is derived following [3].

Construction of the PDFs is implemented in the superclass ParzenWindowHistogramImageToImageMetric.

This implementation of the NormalizedMutualInformation 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's 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:

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