opencv @3.4.3: +contrib not configured correctly

Reported by: jtressle Owned by: stromnov (Andrey Stromnov)
Priority: Normal Milestone:
Component: ports Version: 2.5.4
Keywords: Cc: ifernandolopez (Fernando López Hernández)
Port: opencv

Description (last modified by ryandesign (Ryan Carsten Schmidt))

I'm able to compile Opencv 3.4.3 correctly with +contrib. However, the +contrib portion doesn't work.

Both SIFT and SURF work in 3.4.1. However, they do not work in 3.4.3. You can test by running the following code:

cv::Ptr<cv::xfeatures2d::SIFT> sift = cv::xfeatures2d::SIFT::create();

The last working version of Opencv is in commit 01d8762/macports-ports.

Thanks

Looks like CMAKE for +contrib version needs to be configured with:

    -DOPENCV_ENABLE_NONFREE:BOOL=ON

This flag wasn't enforced on 3.4.1.

According to the duplicate, this is because the algorithm is patent-encumbered. I don't know if we are even legally able to turn it on.
