resampleImageToTarget

Description

Resample image by using another image as target reference. This function uses antsApplyTransform with an identity matrix to achieve proper resampling.

Usage

resampleImageToTarget(
  image,
  target,
  interpType = "linear",
  imagetype = 0,
  verbose = FALSE,
  ...
)

Arguments

image	image to resample
target	image of reference, the output will be in this space
interpType	Choice of interpolator. Supports partial matching. linear nearestNeighbor multiLabel for label images but genericlabel is preferred gaussian bSpline cosineWindowedSinc welchWindowedSinc hammingWindowedSinc lanczosWindowedSinc genericLabel use this for label images
imagetype	choose 0/1/2/3 mapping to scalar/vector/tensor/time-series
verbose	print command and run verbose application of transform.
...	additional arugment passed to antsApplyTransforms C code

Value

output antsImage resampled with target's resolution/origin/orientation/direction

Examples

fname <- getANTsRData("r16")
fi <- antsImageRead(fname)
fi2mm <- resampleImage(fi, c(2, 2), useVoxels = 0, interpType = "linear")
resampled <- resampleImageToTarget(fi2mm, fi)
testthat::expect_error(resampleImageToTarget(fi2mm))
