Thanks for taking care of that, directhex!

SIFT algorithm is patented in US
You received this bug notification because you are a member of Ubuntu
CLI/Mono Uploaders, which is subscribed to autopano-sift in ubuntu.

Status in “autopano-sift” package in Ubuntu: Won't Fix

Bug description:
Binary package hint: autopano-sift

Please remove ‘autopano-sift’ from the ‘universe’ repository (and move it to Medibuntu if possible). The scale-invariant feature transform (SIFT) algorithm used by ‘autopano-sift’ is patented in United States (see [1] and [2]) by the University of British Columbia and therefore cannot be freely used there.
