Apply a precomputed surface sampler to a volume

Usage

apply_surface_sampler(
  sampler,
  vol,
  fun = c("avg", "nn", "mode"),
  sigma = 8,
  fill = 0
)

Arguments

sampler: A sampler object returned by surface_sampler().
vol: A NeuroVol with the same grid as the template used to build the sampler.
fun: Aggregation function: "avg", "nn", or "mode".
sigma: Bandwidth for Gaussian weights when fun = "avg".
fill: Value used when no valid voxels fall within dthresh.

Value

NeuroSurface with mapped data.

Examples

# \donttest{
# Requires surface sampler and volume data
# sampler <- surface_sampler(geometry, vol)
# result <- apply_surface_sampler(sampler, vol)
# }
