Pixel neighbors in 2d array (image) using Python

Question

I have a numpy array like this:

x = np.array([[1,2,3],[4,5,6],[7,8,9]])

I need to create a function let\'s call it \"neighbors\" with the f

Answer 1

I agree with Joe Kingtons response, just an add to the footprints

import numpy as np
from scipy.ndimage import generate_binary_structure
from scipy.ndimage import iterate_structure
foot = np.array(generate_binary_structure(2, 1),dtype=int)

or for bigger/different footprints for ex.

np.array(iterate_structure(foot , 2),dtype=int)
