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.
