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

[Jonas Meurer]

Source: opencv
Version: 2.4.6.1+dfsg-2
Severity: Normal

Hello,

unfortunately, the Debian OpenCV packages don't provide the SIFT and 
SURF modules.

It seems like these modules were outsourced into a nonfree module, and 
need to be enabled explicitely at build time with cmake flag 
"-DBUILD_opencv_nonfree=ON".

I didn't check the license of these modules, but as long as it's 
possible to distribute them in non-free, I suggest to build them (or at 
least make it easy to enable them at build time by simple flag in 
debian/rules).

Here's some further information:

The issue has already been reported to Ubuntu as well:

Kind regards,
