What makes it patent-free?
autopano-sift-C has an implementation of the SIFT technique, and the
alternative panomatic implements SURF. Both algorithms are
apparently patented, so neither tool could go into Fedora.
This was a problem, so Pablo d'Angelo (the original author of Hugin)
wrote cpfind, which uses code from panomatic but has an entirely
novel feature detector.
Is the quality of the output comparable?
Yes, the cpfind in Hugin 2011.0.0 is much more reliable than
autopano-sift-c, but not necessarily faster. Unfortunately 2011.0.0
didn't make it into F15, though it will be in F16.
