function

`skimage.measure._regionprops_utils:perimeter`

source: /dev/scikit-image/src/skimage/measure/_regionprops_utils.py:417

Signature

def perimeter(image, neighborhood = 4)

Summary

Calculate total perimeter of all objects in binary image.

Parameters

image : ndarray of shape (M, N): Binary input image.
neighborhood : 4 or 8, optional: Neighborhood connectivity for border pixel determination. It is used to compute the contour. A higher neighborhood widens the border on which the perimeter is computed.

Returns

perimeter : float: Total perimeter of all objects in binary image.

Examples

import skimage as ski
img_coins = ski.data.coins() > 110

✓

ski.measure.perimeter(img_coins, neighborhood=4)  # doctest: +ELLIPSIS
ski.measure.perimeter(img_coins, neighborhood=8)  # doctest: +ELLIPSIS
