Spatial morphological Grey Opening filterΒΆ
Spatial morphological Grey Opening filter. See Wikipedia for general information.
Parameters
- Raster layer [raster]
- Raster layer to be processed band-wise.
- Function [string]
Python code. See grey_opening, generate_binary_structure, iterate_structure for information on different parameters.
Default:
from scipy.ndimage.morphology import grey_opening, generate_binary_structure, iterate_structure structure = generate_binary_structure(rank=2, connectivity=1) structure = iterate_structure(structure=structure, iterations=1) function = lambda array: grey_opening(array, structure=structure)
Outputs
- Output raster layer [rasterDestination]
- Raster file destination.
