scipy.ndimage.measurements.find_objects(input, max_label=0)

Find objects in a labeled array.

The input must be an array with labeled objects. A list of slices into the array is returned that contain the objects. The list represents a sequence of the numbered objects. If a number is missing, None is returned instead of a slice. If max_label > 0, it gives the largest object number that is searched for, otherwise all are returned.
