maximum
-
skimage.filters.rank.maximum(image, selem, out=None, mask=None, shift_x=False, shift_y=False)
[source] -
Return local maximum of an image.
Parameters: image : 2-D array (uint8, uint16)
Input image.
selem : 2-D array
The neighborhood expressed as a 2-D array of 1’s and 0’s.
out : 2-D array (same dtype as input)
If None, a new array is allocated.
mask : ndarray
Mask array that defines (>0) area of the image included in the local neighborhood. If None, the complete image is used (default).
shift_x, shift_y : int
Offset added to the structuring element center point. Shift is bounded to the structuring element sizes (center must be inside the given structuring element).
Returns: out : 2-D array (same dtype as input image)
Output image.

Notes
The lower algorithm complexity makes
skimage.filters.rank.maximum
more efficient for larger images and structuring elements.Examples
>>> from skimage import data >>> from skimage.morphology import disk >>> from skimage.filters.rank import maximum >>> img = data.camera() >>> out = maximum(img, disk(5))
