scipy.ndimage.measurements.label(input, structure=None, output=None)

Label an array of objects.

The structure that defines the object connections must be symmetric. If no structuring element is provided an element is generated with a squared connectivity equal to one. This function returns a tuple consisting of the array of labels and the number of objects found. If an output array is provided only the number of objects found is returned.
