The forward of ConvOffset2D
contains two part: deformable_im2col
and gemm
. To generalize it to 3D version, the function deformable_im2col
needs a rewrite (deformable_im3d2col
).
Similarly, in backward propagation, following functions should be implemented:
deformable_col2im3d_coord
deformable_col2im3d
In the near future, I may take a try, but don't expect too much.

What would 3d conv change, isn't the offset applied all layers anyways?

Has anyone given this a shot yet?

Hi, you can take a look at: https://github.com/KrakenLeaf/deform_conv_pytorch
Let me know if you find any bugs :)
from deformable-convolution-pytorch.
@KrakenLeaf awesome, awesome, awesome, I'll integrate this into one of my auto segmentation pipelines and let you know!!

Hi @KrakenLeaf,
The 3d deformable convolution is amazing. What about 3d deformable RoI pooling? Do you have the 3d version of pooling layer? if yes please share it.
Thanks

Hi @salmank255 ,
Thanks, but unfortunately I did not implement 3D deformable ROI pooling yet.
But this is definitely something to look at.

Yeah @KrakenLeaf, I am working on it, but didn't complete it yet. If you convert it, please let me know.
Thanks
