Heya Itk-Team,

how can i visualize the downsampled\smooted images at each level of the pyramid for image registration, here i am mostly interested in the fixed image.

Im using itk-elastix for python.

Hey Kendrick,

The multiscale pyramid used in itk-elastix Python is currently internal to registration runs. However, you could generate the equivalent with [ngff-zarr](https://ngff-zarr.readthedocs.io/en/latest/) and visualize it with [itkwidgets](https://itkwidgets.readthedocs.io/en/latest/).

HTH,  
Matt
