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.]
