Registration of 3D stacks

[Yongqiang Chen]

Dear ImageJ experts,

I did two CT scanning. There is a small angle difference between these two scanning stacks. For each scanning, there are around 1000 slices. Could anybody help me register these two image stacks?

Best Regards

If you do not find a way to do this in IJ, one of our researchers used a
program called 3D Slicer to register microCT volumes. That has many methods of
registration.
Perhaps you should take a look:

It is possible to do it in ImageJ, but how easy or difficult it is depends a lot on your samples.
I have found both the plugin "Rigid Registration" from the VIB project,
and the Fiji built-in plugin "Descriptor-based registration (2d/3d)"  to work with my µCT data.
But it takes a lot of work to get perfect results, so you may try something else first.

The above plugins depend on being able to automatically match objects in your scan,
so your data must contain preferably bright spots that can be matched in the two scans.
Can you perhaps post a sample 2D image?
