Function File: watershed (im, conn)

Compute watershed transform.

Computes by immersion

Element connectivity conn, to define the size of objects, can be specified with a numeric scalar (number of elements in the neighborhood):

‘4 or 8’

for 2 dimensional matrices;

‘6, 18 or 26’

for 3 dimensional matrices;

or with a binary matrix representing a connectivity array. Defaults to conndef (ndims (bw), "maximal") which is equivalent to conn of 8 and 26 for 2 and 3 dimensional matrices respectively.
