Hi everyone, I work on a project where I try to track cell and cell division over-time. If cells are well separated, a simple watershed is fine, however, if cells start to overlap it doesn't work anymore. If I had another step using random walker followed by a "join_segmentations" I can split touching cells as in follow: ​ ​So my foreground (the cells) were split in 3 which is what I want, but my background is also split. I might be missing something, but is there an easy way to "unify" my background, while keeping the foreground segmentation? Best, Cedric
