license problem in descriptor.hpp

[fcyella]

• OpenCV => 4.0.1
• Operating System / Platform => Linux,
• Compiler => gcc

In modules/line_descriptor/include/opencv2/line_descriptor/descriptor.hpp, a section between lines 625 and 824 that starts with "Compare doubles by relative error" That appears to come from here: http://www.ipol.im/pub/art/2012/gjmr-lsd/, which has the GNU Afero General Public License.
Seems it's not compatible with opencv_contrib's 3-clause BSD License, Will this be a problem?

@fcyella, thank you! Yes, this is definitely a problem. We will prepare patches to remove this code from the master and 3.4 branches shortly.

I am going to release my company commercial production which is using LineSegmentDetector in OpenCV 3.4.3. Will this be a problem if we will not open our source code?
Thank you!

You should contact with your lawyer.
Don't expect legal-related answers on Internet.

@alalek There is no license on this code. Original code is here and about license it's here

[JLLeitschuh]

Is there a license-compatible version of this logic that will be made available?

[AlexDaniel]

Seriously. I just stumbled upon this. Can't we ask them to relicense that particular piece of code? I just spent an hour trying to work around this issue just to keep my code working.

I just saw this issue. I apologize for the problematic license on the blog post. I've updated it. I also put a copy of the code with an embedded license in github: https://github.com/randomascii/blogstuff/blob/main/FloatingPoint/CompareAsInt/CompareAsInt.cpp

i am happy to annonce that after i send an e-mail to @rafael-grompone-von-gioi he kindly published his Computation of a NFA related to a binomial distribution code with MIT licence. He also states he will be happy to help on restoration of LDS Algorithm in OpenCV.

thank you @rafael-grompone-von-gioi for your great work.
