Hello Team

I was trying to extract features from brain MRI images using pyradiomics.

According to this article (Page4)  
[https://rdcu.be/cTh2N](https://rdcu.be/cTh2N)

Two essential steps before the feature extraction are _Interpolation to isotropic voxel spacing_ and _intensity outlier filtering_

Does pyradiomics provides such functions?

I learned a little bit about pyradiomics parameter customization from this source, I wonder if that could help?

> <https://github.com/AIM-Harvard/pyradiomics/blob/master/docs/customization.rst>

Namely, under **setting** , it mentioned two functions \* removeOutliers\* and _interpolator_, although i am not positive if they are the functions I am looking for. Could you help me on that?

Thank  
Have a good day
