template<class TElastix>
class elastix::RandomSampler< TElastix >
An interpolator based on the itk::ImageRandomSampler.
This image sampler randomly samples 'NumberOfSamples' voxels in the InputImageRegion. Voxels may be selected multiple times. If a mask is given, the sampler tries to find samples within the mask. If the mask is very sparse, this may take some time. In this case, consider using the RandomSparseMask image sampler.
This sampler is suitable to used in combination with the NewSamplesEveryIteration parameter (defined in the elx::OptimizerBase).
The parameters used in this class are:
- Parameters
ImageSampler: Select this image sampler as follows:
(ImageSampler "Random")
NumberOfSpatialSamples: The number of image voxels used for computing the metric value and its derivative in each iteration. Must be given for each resolution.
example: (NumberOfSpatialSamples 2048 2048 4000)
The default is 5000.
