Here is an interesting paper to the topic:

A Comparison of Four Algorithm s for Estimating tD Rigid Transformations

http://www.homepages.inf.ed.ac.uk/rbf/MY_DAI_OLD_FTP/rp765.pdf

Actually the Horn approach (unit quaternions) and the above mentioned (SVD?) are pretty much equivalent

I am sorry for the inconvenience caused by the missing crossprod function files. I uploaded the new version and it should be online soon.
Cheers
