Hi,

I'm not sure whether this might be of help but I think this is somewhat similar to registration of moving objects across images.
One approach of dealing with this, is presented in the following article:

IEEE TRANSACTIONS ON IMAGE PROCESSING, VOL. 15, NO. 7, JULY 2006, A Correlation-Based Approach to Calculate Rotation and Translation of Moving Cells, Cyrus A. Wilson and Julie A. Theriot

This approach is intended to retrieve the rotation angle and translation of an object, but could also be used for finding your object I guess.
I'm just not sure whether imageJ is capable of displaying the polar transformed magnitude spectra (I think there's a plugin for that).
Kind regards,
Winnok

Hi Michael,

thank you for your reply. I already suspected that this was not going to be
easy. I will try to solve the problem with a batch of manually rotated
templates. If someone has another idea I would be very grateful

Thanks,

Felix
