#include <elxRandomCoordinateSampler.h>

Detailed Description

template<class TElastix>
class elastix::RandomCoordinateSampler< TElastix >

An interpolator based on the itk::ImageRandomCoordinateSampler.

This image sampler randomly samples 'NumberOfSamples' coordinates in the InputImageRegion. 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. The RandomCoordinate sampler samples not only positions that correspond to voxels, but also positions between voxels. An interpolator for the fixed image is thus required. A B-spline interpolator is used, the order of which can be specified by the user. Typically, the RandomCoordinate gives a smoother cost function, because the so-called 'grid-effect' is avoided.

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 "RandomCoordinate")

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.

UseRandomSampleRegion: Defines whether to randomly select a subregion of the image in each iteration. When set to "true", also specify the SampleRegionSize. By setting this option to "true", in combination with the NewSamplesEveryIteration parameter, a "localised" similarity measure is obtained. This can give better performance in case of the presence of large inhomogeneities in the image, for example.
example: (UseRandomSampleRegion "true")
Default: false.

SampleRegionSize: the size of the subregions that are selected when using the UseRandomSampleRegion option. The size should be specified in mm, for each dimension. As a rule of thumb, you may try a value ~1/3 of the image size.
example: (SampleRegionSize 50.0 50.0 50.0)
You can also specify one number, which will be used for all dimensions. Also, you can specify different values for each resolution:
example: (SampleRegionSize 50.0 50.0 50.0 30.0 30.0 30.0)
In this example, in the first resolution 50mm is used for each of the 3 dimensions, and in the second resolution 30mm.
Default: sampleRegionSize[i] = min ( fixedImageSize[i], max_i ( fixedImageSize[i]/3 ) ), with fixedImageSize in mm. So, approximately 1/3 of the fixed image size.

FixedImageBSplineInterpolationOrder: When using a RandomCoordinate sampler, the fixed image needs to be interpolated. This is done using a B-spline interpolator. With this option you can specify the order of interpolation.
example: (FixedImageBSplineInterpolationOrder 0 0 1)
Default value: 1. The parameter can be specified for each resolution.
