Unsharp masking — wbt_unsharp_masking • whitebox

An image sharpening technique that enhances edges.

Usage

wbt_unsharp_masking(
  input,
  output,
  sigma = 0.75,
  amount = 100,
  threshold = 0,
  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.
sigma: Standard deviation distance in pixels.
amount: A percentage and controls the magnitude of each overshoot.
threshold: Controls the minimal brightness change that will be sharpened.
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.
