smooth_hrf_assignments: Smooth HRF Assignments

In bbuchsbaum/fmrireg: R package for the anlysis of fmri data

Smooth HRF Assignments

Description

This function tries to smooth out a voxel-wise label map of HRF assignments by iterating over each voxel, checking its neighbors, picking the "most common" neighbor label if that reduces cost, etc.

Usage

smooth_hrf_assignments(
  reassigned_hrfs,
  L_best_hrfs,
  voxel_coords,
  lambda = 0.1,
  n_iterations = 5,
  k = 6
)

Arguments

reassigned_hrfs	An integer vector of length n_voxels
L_best_hrfs	A matrix of reference HRFs for each label
voxel_coords	A matrix of voxel coordinates (n_voxels x 3), or similar
lambda	Not actually used, but left here as a param
n_iterations	Number of smoothing passes
k	Number of neighbors

Value

A vector of the same length as reassigned_hrfs, updated (smoothed)
