1997.7.8  Start by choosing an arbitrary seed pixel and compare it with neighbouring pixels (see Fig 37). Region is grown from the seed pixel by adding in neighbouring pixels that are similar, increasing the size of the region. When the growth of one region stops we simply choose another seed pixel which does not yet belong to any region and start again.
