Spatial Morphological Binary Fill Holes

Applies binary_fill_holes morphology filter to image.

See the following Cookbook Recipes on how to apply filters: Filtering , Generic Filter

Parameters

Raster [raster]

Specify input raster.

Code [string]

Python code. See scipy.ndimage.binary_fill_holes for information on different parameters. At first, the structuring element will be defined (scipy.ndimage.generate_binary_structure). By default, its dimensions are always equal to 3. The connectivity parameter defines the type of neighborhood. In order create a bigger structuring element, the parameters in iterate_structure have to be altered (e.g. iterations=2 will increase the size to 5). Alternatively, a custom numpy array can be used as structural element.

Default:

from scipy.ndimage.morphology import binary_fill_holes, generate_binary_structure, iterate_structure

structure = generate_binary_structure(rank=2, connectivity=1)
structure = iterate_structure(structure=structure, iterations=1)
function = lambda array: binary_fill_holes(array, structure=structure)

Outputs

Output Raster [rasterDestination]

Specify output path for raster.
