Hi Gil,
have a look at the Descriptor-based registration and Descriptor-based series registration plugins. For that, you would have to download Fiji (
http://fiji.sc/) which is a distribution of ImageJ. After updating Fiji, you will find the plugins under Plugins->Registration. You will find an explanation of how it works in this paper:
http://www.nature.com/nmeth/journal/v7/n6/full/nmeth0610-418.html (but it will work with anything, not only beads)
I hope it might just do what you need ... if you need the API and not only the plugins, let me know I can give you more insight ...
Nice greetings,
Stephan
