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.

You can see from the following information about the patent which is for Debian.

Ubuntu because it is a commercial company, I think the issue is more difficult.
