I noticed a recent publication in IEEE Transactions on Image Processing today:
HAIRIS: A Method for Automatic Image Registration Through
Histogram-Based Image Segmentation
Hernâni Gonçalves, José Alberto Gonçalves, and Luís Corte-Real, Member, IEEE
This could be a fun project! It seems to be a fairly robust method
for doing registration without any tweaking parameters.
I've also considered some other registration algorithms based on
projections of the log-polar transform, in addition to existing code I
wrote to do feature-based registration. Registration is one of the
few "solved problems" that always causes problems!
If you have bored students over the holidays, send them my way...
