applying transform to other images

[soupault]

@alfonmedela This is currently not implemented, but I will consider it high-priority in my next iteration with the code. Or... You are always welcome to submit a PR. 🙂

Did you find a solution to this @cabaker7 ? I am having the same problem and I can't find a straightforward way to solve it

[Iamlearn]

Hello, I have the same problem. Have you solved it?

[philippe2toulouse]

I also have the same problem. Have you been able to implement it?
thks :-)

Any solution ? I used pyelastix to register two medical images, i wanna reproduce the same transformation on their respective masks(for segmentation purposes) , i cant find a way to exploit the resulting field to do so.

Hello,
@FakerAmine I think it might be possible to use the field and pass it somehow to another library like SimpleITK to generate a deformation field. However, I'm not sure how to do it, for the time being when I apply the deformation in this way the result is far from the expected, could be related to how the axes are defined. Not sure. Could also be other libraries to work with the numpy array directly, maybe scipy has something to work with this?
I was working based on this with SimpleITK in case it is useful: SimpleITK/SimpleITK#1285
If anyone can figure it out please share. I'll do the same.

Thanks

@manuel-lincbiotech Thank you ! I will try doing that !

Hello,

@FakerAmine, got any positive results using the SimpleITK route?
I am facing the same issue right now.

Thanks

pyelastix is really great for registration. But I solved the same problem as you mentioned using ANTsPy. You can follow this example for more information https://github.com/ANTsX/ANTsPy/blob/master/tutorials/concatenateRegistrations.ipynb
