internal smoothing function Function that does the smoothing on individual image array

Usage

internal_smooth(
  image,
  method = c("median", "iso", "box"),
  iter = 1,
  sigma = 1,
  box = 20,
  threshold = 0,
  neuman = TRUE,
  gaussian = TRUE,
  na.rm = FALSE,
  across_levels = "min"
)

Arguments

image: cimg array
method: character describing smoothing method to use "median" , "iso" or "box" or a combination of them.
iter: numeric - number of smoothing iteration
sigma: numeric - standard deviation associated with isoblur (Gaussian)
box: numeric describing box size (centered around center pixel) for smoothing
threshold: numeric - discard pixels that are too low in value (cutoff threshold only applied in box/median blurs).
neuman: logical describing If Neumann boundary conditions should be used, Dirichlet otherwise (default true, Neumann)
gaussian: logical - use gaussian filter
na.rm: logical describing if NA values should be removed
across_levels: character - method used to account for multiple smoothing levels (see details). Select from: "min","mean", "max"
