Detailed Description

template<class TElastix>
class elastix::NormalizedMutualInformationMetric< TElastix >

A metric based on the itk::ParzenWindowNormalizedMutualInformationImageToImageMetric.

The parameters used in this class are:

Metric: Select this metric as follows:
(Metric "NormalizedMutualInformation")

NumberOfHistogramBins: The size of the histogram. Must be given for each resolution, or for all resolutions at once.
example: (NumberOfHistogramBins 32 32 64)
The default is 32 for each resolution.

NumberOfFixedHistogramBins: The size of the histogram in the fixed dimension. Can be given for each resolution, or for all resolutions at once. If not given, NumberOfHistograms is used.
example: (NumberOfFixedHistogramBins 32 32 64)
The default is the value of NumberOfHistograms.

NumberOfMovingHistogramBins: The size of the histogram in the fixed dimension. Can be given for each resolution, or for all resolutions at once. If not given, NumberOfHistograms is used.
example: (NumberOfMovingHistogramBins 32 32 64)
The default is the value of NumberOfHistograms.

FixedKernelBSplineOrder: The B-spline order of the Parzen window, used to estimate the joint histogram. Can be given for each resolution, or for all resolutions at once.
example: (FixedKernelBSplineOrder 0 1 1)
The default value is 0.

MovingKernelBSplineOrder: The B-spline order of the Parzen window, used to estimate the joint histogram. Can be given for each resolution, or for all resolutions at once.
example: (MovingKernelBSplineOrder 3 3 3)
The default value is 3.

FixedLimitRangeRatio: The relative extension of the intensity range of the fixed image.
If your image has gray values from 0 to 1000 and the FixedLimitRangeRatio is 0.001, the joint histogram will expect fixed image gray values from -0.001 to 1000.001. This may be useful if you use high order B-spline interpolator for the fixed image.
example: (FixedLimitRangeRatio 0.001 0.01 0.01)
The default value is 0.01. Can be given for each resolution, or for all resolutions at once.

MovingLimitRangeRatio: The relative extension of the intensity range of the moving image.
If your image has gray values from 0 to 1000 and the MovingLimitRangeRatio is 0.001, the joint histogram will expect moving image gray values from -0.001 to 1000.001. This may be useful if you use high order B-spline interpolator for the moving image.
example: (MovingLimitRangeRatio 0.001 0.01 0.01)
The default value is 0.01. Can be given for each resolution, or for all resolutions at once.
