scipy.ndimage.watershed_ift(input, markers, structure=None, output=None)[source]¶ Apply watershed from markers using image foresting transform algorithm.
- Parameters
- inputarray_like
Input.
- markersarray_like
Markers are points within each watershed that form the beginning of the process. Negative markers are considered background markers which are processed after the other markers.
- structurestructure element, optional
A structuring element defining the connectivity of the object can be provided. If None, an element is generated with a squared connectivity equal to one.
- outputndarray, optional
An output array can optionally be provided. The same shape as input.
- Returns
- watershed_iftndarray
Output. Same shape as input.
