Re: [Numpy-discussion] position of objects?

The procedure you show below seems to be based on a normal watershed. I am not completely sure how the Image-J implementation works, but one way to do that would be to do a watershed on the distance transform of that image (actually you would use the negative of the distance transform, with the local minima of that as the seeds). You could do that with watershed_ift, in this case it would give you two labeled objects, that in contrast to your example would however touch each other. To do the exact same as below a watershed is needed that also gives watershed lines.
Hi Peter, I thought I'd try your suggestion above but I'm falling short. Where I stall is at local minima (or local maxima if you don't invert the image). Currently there is no local minima (or maxima) function in nd_image is there (or am I missing it)? Bob
