virtual void itk::ImageGridSampler< TInputImage >::SetNumberOfSamples | ( | unsigned long | nrofsamples | ) | [virtual] |
Define an isotropic SampleGridSpacing such that the desired number of samples is approximately realised. The following formula is used:
spacing = max[ 1, round( (availablevoxels/nrofsamples)^(1/dimension) ) ], with availablevoxels = nr of voxels in input image region.
The InputImageRegion needs to be specified beforehand. A mask is ignored, so the realised number of samples could be significantly lower than expected. However, the sample grid spacing is recomputed in the update phase, when the bounding box of the mask is known. Supplying nrofsamples=0 turns off the (re)computation of the SampleGridSpacing. Once nrofsamples=0 has been given, the last computed SampleGridSpacing is simply considered as a user parameter, which is not modified automatically anymore.
This function overrules any previous calls to SetSampleGridSpacing.
void itk::ImageGridSampler< TInputImage >::SetSampleGridSpacing | ( | SampleGridSpacingType | arg | ) | [inline] |
Set/Get the sample grid spacing for each dimension (only integer factors) This function overrules previous calls to SetNumberOfSamples. Moreover, it calls SetNumberOfSamples(0) (see below), to make sure that the user-set sample grid spacing is never overruled.
