binary-erosion

binary_erosion

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].
