This _png_init_filter_functions_neon "undefined symbols for architecture arm64" issue is fixed by this commit, I think:

https://github.com/opencv/opencv/comm...

Effectively, -DENABLE_NEON=ON is incorrectly skipped on arm64 during the build before this commit.

See my answer at StackOverflow for more details:

To minimize risk, I cloned, checked out the 3.1.0 tag, and cherry-picked just the 262a52fcommit, and have built with that using instructions from https://github.com/opencv/opencv/tree... -- this appears to have worked.
