Lee sigma filter — wbt_lee_sigma

Performs a Lee (Sigma) smoothing filter on an image.

Usage

wbt_lee_sigma_filter(
  input,
  output,
  filterx = 11,
  filtery = 11,
  sigma = 10,
  m = 5,
  wd = NULL,
  verbose_mode = NULL,
  compress_rasters = NULL,
  command_only = FALSE
)

Arguments

input: Input raster file path. See wbt_file_path() for details.
output: Output raster file.
filterx: Size of the filter kernel in the x-direction.
filtery: Size of the filter kernel in the y-direction.
sigma: Sigma value should be related to the standard deviation of the distribution of image speckle noise.
m: M-threshold value the minimum allowable number of pixels within the intensity range.
wd: Changes the working directory. Default: NULL will use the value in WhiteboxTools settings, see wbt_wd() for details.
verbose_mode: Sets verbose mode. If verbose mode is FALSE, tools will not print output messages. Default: NULL will use the value in WhiteboxTools settings, see wbt_verbose() for details.
compress_rasters: Sets the flag used by 'WhiteboxTools' to determine whether to use compression for output rasters. Default: NULL will use the value in WhiteboxTools settings, see wbt_compress_rasters() for details.
command_only: Return command that would be executed by system() rather than running tool. Default: FALSE.

Value

Returns the tool text outputs.
