convex-hull-object

convex_hull_object

skimage.morphology.convex_hull_object(image, neighbors=8) [source]

Compute the convex hull image of individual objects in a binary image.

The convex hull is the set of pixels included in the smallest convex polygon that surround all white pixels in the input image.

Parameters:	image : (M, N) array Binary input image. neighbors : {4, 8}, int Whether to use 4- or 8-connectivity.
Returns:	hull : ndarray of bool Binary image with pixels in convex hull set to True.

Notes

This function uses skimage.morphology.label to define unique objects, finds the convex hull of each using convex_hull_image, and combines these regions with logical OR. Be aware the convex hulls of unconnected objects may overlap in the result. If this is suspected, consider using convex_hull_image separately on each object.
