laplace
-
skimage.filters.laplace(image, ksize=3, mask=None)
[source] -
Find the edges of an image using the Laplace operator.
Parameters: image : ndarray
Image to process.
ksize : int, optional
Define the size of the discrete Laplacian operator such that it will have a size of (ksize,) * image.ndim.
mask : ndarray, 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
The Laplace edge map.
Notes
The Laplacian operator is generated using the function skimage.restoration.uft.laplacian().
