subdivide_polygon

skimage.measure.subdivide_polygon(coords, degree=2, preserve_ends=False) [source]

Subdivision of polygonal curves using B-Splines.

Note that the resulting curve is always within the convex hull of the original polygon. Circular polygons stay closed after subdivision.

Parameters:

Parameters:	coords : (N, 2) array Coordinate array. degree : {1, 2, 3, 4, 5, 6, 7}, optional Degree of B-Spline. Default is 2. preserve_ends : bool, optional Preserve first and last coordinate of non-circular polygon. Default is False.
Returns:	coords : (M, 2) array Subdivided coordinate array.

coords : (N, 2) array

Coordinate array.

degree : {1, 2, 3, 4, 5, 6, 7}, optional

Degree of B-Spline. Default is 2.

preserve_ends : bool, optional

Preserve first and last coordinate of non-circular polygon. Default is False.

Returns:

coords : (M, 2) array

Subdivided coordinate array.
