<div dir="ltr">The greedy approaches, like MorphologicalWatershedFromMarkers, require 2 seeds. One is the background seed. Sometimes that can be something very simple like the image boundary. The advantage of greedy approaches is that you don't need to specify stopping conditions. The cost is obviously the extra seed. Another advantage is that most  of the methods naturally support lots of independent seeds, if you want them.</div><div class="gmail_extra"><br><div class="gmail_quote">On Sat, Feb 11, 2017 at 7:45 AM, Abdelkhalek Bakkari <span dir="ltr"><<a href="mailto:bakkari.abdelkhalek@hotmail.fr" target="_blank">bakkari.abdelkhalek@hotmail.fr</a>></span> wrote:<br><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex">
