__call__(data)

__call__(data: Subject) -> Subject
__call__(data: ImageT) -> ImageT
__call__(data: torch.Tensor) -> torch.Tensor
__call__(data: np.ndarray) -> np.ndarray
__call__(data: sitk.Image) -> sitk.Image
__call__(data: dict[str, object]) -> dict[str, object]
__call__(data: nib.Nifti1Image) -> nib.Nifti1Image

Transform data and return a result of the same type.

Parameters:

Name Type Description Default
data TypeTransformInput

Instance of torchio.Subject, 4D torch.Tensor or numpy.ndarray with dimensions \((C, W, H, D)\), where \(C\) is the number of channels and \(W, H, D\) are the spatial dimensions. If the input is a tensor, the affine matrix will be set to identity. Other valid input types are a SimpleITK image, a torchio.Image, a NiBabel Nifti1 image or a dict. The output type is the same as the input type.

required

to_hydra_config()

Return a dictionary representation of the transform for Hydra instantiation.
