hull.retain.along.axis: Copy the first *n* foreground voxel values.

In fsbrain: Managing and Visualizing Brain Surface Data

Copy the first *n* foreground voxel values.

Description

Copy the first *n* foreground voxel values along the axis and direction from the volume to the hull, thus adding foreground voxels to the hull.

Usage

hull.retain.along.axis(
  volume,
  hull,
  dim_check = 2L,
  upwards = TRUE,
  thickness = 1L
)

Arguments

volume	numeric 3d array, the full source volume.
hull	numeric 3d array, the input hull volume.
dim_check	integer, the array dimension to use. Must be 1L, 2L or 3L.
upwards	logical, whether to use upwards direction (increasing indices) in the array dimension
thickness	integer, the width of the border in voxels, i.e., how many of the foreground voxels to keep

Value

numeric 3d array, the updated hull volume.
