Dose it support 4d interpolation?

[realyyz]

I have a series of the ground truth of the segmentation of 3d images on different time step, I would like to make the interpolation. But I didn't succeed. This is what I got:

---

I sincerely appreciate your help!

ValueError(f'Unexpected/not yet supported output.type {output.type}') seems to be related to WASM wrapping. It is possible 4D images are not wrapped. @thewtex might provide more insight or advice.

Thank you for your reply. This is the code that I use to test during 4d:

---

image_4d = np.zeros((3, 100, 100, 100), dtype=np.int16) image = itk.GetImageFromArray(image_4d) image_dict = itk.dict_from_image(image) from itkwasm import Image itkwasm_image = Image(**image_dict) filled = morphological_contour_interpolation(itkwasm_image)

I have tried the similar code in 3d, it preforms very well, but when it comes to 4d, there are errors.

I added 4D support to wasm in #121, built and pushed as 1.1.0. Please give it a try and let us know how it goes.

@dzenanz @thewtex Thank you for your help, I have successfully make the interpolation in 3d!
