Detailed Description

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

Computes similarity between two images to be registered.

This metric computes the alpha-Mutual Information (aMI) between two multi-channeled data sets. Said otherwise, given two sets of features, the aMI between them is calculated. Since for higher dimensional aMI it is infeasible to compute high dimensional joint histograms, here we adopt a framework based on the length of certain graphs, see Neemuchwala. Specifically, we use the k-Nearest Neighbour (kNN) graph, using an implementation provided by the Approximate Nearest Neighbour (ANN) software package.

Note that the feature image are given beforehand, and that values are calculated by interpolation on the transformed point. For some features, it would be better (but slower) to first apply the transform on the image and then recalculate the feature.

All the technical details can be found in:

◆ ComputeListSampleValuesAndDerivativePlusJacobian()

		SpatialDerivativeContainerType &	spatialDerivatives
	)		const

private

This function takes the fixed image samples from the ImageSampler and puts them in the listSampleFixed, together with the fixed feature image samples. Also the corresponding moving image values and moving feature values are computed and put into listSampleMoving. The concatenation is put into listSampleJoint. If desired, i.e. if doDerivative is true, then also things needed to compute the derivative of the cost function to the transform parameters are computed:

The sparse Jacobian of the transformation (dT/dmu).
The spatial derivatives of the moving (feature) images (dm/dx).
