skimage.morphology.binary_erosion(image, selem=None, *args, **kwargs)
[source] -
Return fast binary morphological erosion of an image.
This function returns the same result as greyscale erosion but performs faster for binary images.
Morphological erosion sets a pixel at
(i,j)
to the minimum over all pixels in the neighborhood centered at(i,j)
. Erosion shrinks bright regions and enlarges dark regions.Parameters: image : ndarray
Binary input image.
selem : ndarray, optional
The neighborhood expressed as a 2-D array of 1’s and 0’s. If None, use cross-shaped structuring element (connectivity=1).
out : ndarray of bool, optional
The array to store the result of the morphology. If None is passed, a new array will be allocated.
Returns: eroded : ndarray of bool or uint
The result of the morphological erosion taking values in
[False, True]
