[ITK] [ITK-users] region inside points

[Gib Bogle]

Maybe there is a way to use a rolling ball.  Richard Beare has some morphological filters that might be applicable, but I think it will always be a bit complicated.

Hi Gib.

Thanks for the quick response. The problem of using dilation and skeletonization is that some times the gap between pixels is big, and I will have to work with different and big structural elements to be sure that all the gaps were eliminated.

I was hoping to find a class that works similar to a convex hull (it does not have to be convex) algorithm and then find the region surrounded by the hull.

Thanks

Sorry, I misread your post Fabian - I read it as you wanting the region _surrounding_ the white pixels.  But dilate might be usable to fill the gaps, followed by skeletonization.

Maybe you could do something with BinaryImageDilateFilter.

Hi all.

I have an image that represents some pixels over the surface of an object. Pixels in the surface have value of 1 while any other pixel has value of 0.
The pixels are not a continuous line, there are some gaps between pixels. I want to know the region surrounded by the white pixels in my image.

I will be working with 2D and 3D data. Is there any class implemented in ITK that I can use?

Thanks
