def roberts ( image , mask = None )

Summary

Find the edge magnitude using Roberts' cross operator.

Parameters

image : ndarray of shape (M, N): Image to process.
mask : ndarray of shape (M, N), optional: An optional mask to limit the application to a certain area. Note that pixels surrounding masked regions are also masked to prevent masked regions from affecting the result.

Returns

output : ndarray of shape (M, N) and dtype float: The Roberts' Cross edge map.

Examples

from skimage import data
camera = data.camera()
from skimage import filters
edges = filters.roberts(camera)
