i.destripe

Destripes regularly, about vertical, striped image using Fourier.

i.destripe input=name harmonic=integer output=name [--overwrite] [--verbose] [--quiet] [--qq] [--ui]

Example:

i.destripe input=name harmonic=8 output=name

grass.script.run_command("i.destripe", input, harmonic=8, output, overwrite=None, verbose=None, quiet=None, superquiet=None)

Example:

gs.run_command("i.destripe", input="name", harmonic=8, output="name")

grass.tools.Tools.i_destripe(input, harmonic=8, output, overwrite=None, verbose=None, quiet=None, superquiet=None)

Example:

tools = Tools()
tools.i_destripe(input="name", harmonic=8, output="name")

This grass.tools API is experimental in version 8.5 and expected to be stable in version 8.6.

Parameters

input=name [required]
    Name of input raster map
harmonic=integer [required]
    Number of harmonics to use (less is smoother output)
    Default: 8
output=name [required]
    Name for output raster map
--overwrite
    Allow output files to overwrite existing files
--help
    Print usage summary
--verbose
    Verbose module output
--quiet
    Quiet module output
--qq
    Very quiet module output
--ui
    Force launching GUI dialog

input : str, required
    Name of input raster map
    Used as: input, raster, name
harmonic : int, required
    Number of harmonics to use (less is smoother output)
    Default: 8
output : str, required
    Name for output raster map
    Used as: output, raster, name
overwrite : bool, optional
    Allow output files to overwrite existing files
    Default: None
verbose : bool, optional
    Verbose module output
    Default: None
quiet : bool, optional
    Quiet module output
    Default: None
superquiet : bool, optional
    Very quiet module output
    Default: None

input : str | np.ndarray, required
    Name of input raster map
    Used as: input, raster, name
harmonic : int, required
    Number of harmonics to use (less is smoother output)
    Default: 8
output : str | type(np.ndarray) | type(np.array) | type(gs.array.array), required
    Name for output raster map
    Used as: output, raster, name
overwrite : bool, optional
    Allow output files to overwrite existing files
    Default: None
verbose : bool, optional
    Verbose module output
    Default: None
quiet : bool, optional
    Quiet module output
    Default: None
superquiet : bool, optional
    Very quiet module output
    Default: None

Returns:

result : grass.tools.support.ToolResult | np.ndarray | tuple[np.ndarray] | None
If the tool produces text as standard output, a ToolResult object will be returned. Otherwise, None will be returned. If an array type (e.g., np.ndarray) is used for one of the raster outputs, the result will be an array and will have the shape corresponding to the computational region. If an array type is used for more than one raster output, the result will be a tuple of arrays.

DESCRIPTION

i.destripe Destripes in a row-based Fourier smoothing way. Requires a near vertical striping. Input:

  • Number of harmonics to use for reconstruction (less is smoother output).
