Bug#734373: OpenCV: please build SIFT and SURF modules

[Matthieu Tourne]

Sorry, a little late to this conversation.

Could there be a package libopencv-nonfree-dev by any chance ?

SIFT and SURF are indeed patented, but there have been no patent disputes
so far.
Also there are a lot of other free invariant features detectors /
descriptors that one can use if patents become a real issue.

For now it is just convenient to use Sift as it works well in most cases.

Cheers,
Matthieu
