Hi Jordi, All, Thanks for this. I'm trying to get a segmentation tree from OTB's watershed segmentation method. I understand that varying the "flood level" gives you different output, but I don't see how the integer labels assigned to each segment make sense with each other in a tree/hierarchy, and I don't see how to generate this, as you suggested below a couple years ago.
Could somebody point me in the right direction on this? How might I get a reference table of parent/child relations in the segments, and/or get some programmatic segmentation tree to work with? Thanks :) P On Thursday, July 4, 2013 at 4:16:26 AM UTC-4, Jordi Inglada wrote: > > Hi, > > OTB provides several multi-scale segmentation filters.
