The parameters used in this class are:

Parameters: Metric: Select this metric as follows:
(Metric "DistancePreservingRigidityPenalty")

Parameters

SegmentedImageName: The file name of the image to specify the rigidity index of voxels in the fixed image. The image has only non-integer values as follows: 1) background: 0, 2) rigid region1: 1, 3) rigid region2: 2, and so on.

example: (SegmentedImageName "BoneSegmentation.mhd")

Parameters

PenaltyGridSpacingInVoxels: defines the grid spacing with which the rigidity penalty is calculated. In this current version, the grid spacing is set to be constant over different resolutions.

In the publication above, the grid spacing was set as [4, 4, 1].
