Hi all,

I need to do the data augmentation used by the 3-D Unet work (paper link): “Besides rotation, scaling and gray value augmentation, we apply a smooth dense deformation field on both data and ground truth labels. For this, we sample random vectors from a normal distribution with standard deviation of 4 in a grid with a spacing of 32 voxels in each direction and then apply a B-spline interpolation.”

Can I achieve this with any Slicer module? Hope for some advice. Thanks a lot.
