Suggested parameters for deformable motion correction for a time series.

This function, by default, regularizes the total deformation field to produce a a constrained diffeomorphic motion correction of a time series. Full custom by passing the same parameters that one would pass to antsRegistration.

timeSeriesMotionCorrect(fixedStaticImage, movingTimeSeries, totalSigma,
  flowSigma, regIterations = c(50, 50, 10), ...)

Arguments

fixedStaticImage	fixed static image
movingTimeSeries	time series image to map to the fixed space
totalSigma	regularization for total deformation field
flowSigma	regularization for update deformation field
regIterations	deformable registration iterations / multi-resolution parameters
...	parameters to pass to antsRegistration

Value

deformed images

Examples

library( magrittr )
library( ANTsRCore )
library( ANTsR )
temp1 = resampleImage( ri(1), 4 )
temp2 = resampleImage( ri(2), 4 )
temp3 = resampleImage( ri(1), 2 )
tarspace = makeImage( c( dim( temp1 ), 2 ), spacing = c( 4, 4, 1 ) )
pdcr = mergeListToNDImage( tarspace, list( temp1, temp2 ) )
reg = timeSeriesMotionCorrect( temp3, pdcr )
