I understand that the processing speed of OpenCV can be improved by using a nonfree module. And, I also understand that many users want to use this module. I think you also know that, because it contains the problem of patent, I have been removed from the source code in Debian this module. I do not know whether there is a need to remove the source code, but think of safety, I am that you do not distribute the source code in Debian. http://www.cs.ubc.ca/~lowe/keypoints/ You can see from the following information about the patent which is for Debian. http://www.debian.org/legal/patent http://www.debian.org/reports/patent-faq.en.html > > Here's some further information: > > http://stackoverflow.com/questions/18561910/opencv-python-cant-use-surf-sift > > The issue has already been reported to Ubuntu as well: > https://bugs.launchpad.net/ubuntu/+source/opencv/+bug/1101049 Ubuntu because it is a commercial company, I think the issue is more difficult. > > Kind regards, > jonas IANAL, if you have more infomation, could you teach me about this problem?
