resampleImage.Rd
Resample image by spacing or number of voxels with various interpolators. Works with multi-channel images.
resampleImage(image, resampleParams, useVoxels = FALSE, interpType = "nearestneighbor")
image | input antsImage |
---|---|
resampleParams | vector of size dimension with numeric values |
useVoxels | true means interpret resample params as voxel counts |
interpType | one of 0 (linear), 1 (nearestNeighbor), 2 (gaussian), 3 (windowedSinc), 4 (bspline). The user can pass either a numeric or character argument here. |
