If you mean elastic montage then you would need no mipmaps, just for
final rendering (generating the scale levels costs almost nothing).  If
you mean elastic alignment across layers then you will need the mipmaps
before because it will use them to save time loading images.

Do you know this project?

https://github.com/saalfeldlab/parallel-elastic-alignment

It's pretty messy but may have a lot of code that you could reuse.

Best,
Stephan
