He was asking *how?*.  You are asking *why?*.  Both are fair
questions.

You wondered why a basic threshold wouldn't work.  I think his reply
was that he wanted to select a *particular* contour.  When there are
several peaks in the data then a simple threshold will not work.  As I
pointed out the hardest part in the algorithm I gave is selecting the
right contour.  [And I gave a posible heuristic to decide.]
