Seeded Watershed
Parameters
----------
surface : image
markers : image
initial markers (must be a labeled image)
Bc : ndarray, optional
structuring element (default: 3x3 cross)
return_lines : boolean, optional
whether to return separating lines (in addition to regions)
Returns
-------
W : Regions image (i.e., W[i,j] == region for pixel (i,j))
WL : Lines image (`if return_lines==True`)
