Hi Peter,
I have OpenCV 2.4.9.1.
Could you please provide more information about why you can't load
pix_opencv_threshold ?
You should have some error in Pd console, and as suggested by Antoine
Rousseau please start pd with -verbose flag and switch console to log mode
"4 all".
When you add a [declare -lib pix_opencv] , do you see a message on the Pd
Console ?
Something like :
pix_opencv 0.4 library by Antoine Villeret 2012-2014
based on work by Yves Degoyon and Lluis Gomez i Bigorda
built on Mar 14 2016
without non-free features
and without FaceTracker.
If you don't then pix_opencv is not loaded but Pd should tell you why.
Best
Antoine
