Hi Jerome,

Thanks a lot for the gist, I'll give it a try.

The video does not seem to be working, Youtube says "This video is
currently unavailable".

On another mailing list (ITK), I've been advised to use TrackEM2 for
manual segmentation with ImageJ/Fiji.

I'll look into it as well.

Kind regards,

Kevin
