Hello everyone,
I am new to this amazing library. I am working on classification of lymph nodes using deep learning, therefore, I need to do data augmentation of 3D ROIs (of shape 32X32X32) like 3d rotation, 3d translation along a random vector, etc. I tried to use Transforms like Euler3D but it’s showing error when I use numpy 3d array. In examples Euler3d and other transforms are applied on data points.
Please help me figure out how to apply those useful transform to a 3d numpy array. [Transforms](http://insightsoftwareconsortium.github.io/SimpleITK-Notebooks/Python_html/22_Transforms.html). I think this topic will also help others in my domain.
Thanking You

Hello @jayant_prakash,
You should not be working directly with augmentation of numpy arrays, rather use SimpleITK images. I believe [this Jupyter notebook](https://github.com/InsightSoftwareConsortium/SimpleITK-Notebooks/blob/master/Python/70_Data_Augmentation.ipynb) does what you want, data augmentation in 3D.
If not, please be more specific with respect to what you want to do and we’ll try our best to help.
