Abeer's profile - activity

I've recently downloaded opencv3.1.0 on windows 7 desktop with microsoft visual studio 2015.

But when I try to run the code it gives me these errors for the following line of code // create a tracker object Ptr<tracker> tracker = Tracker::create("KCF"); errors: 1- identifier "Tracker" is undefined AbeerTracker
2- name followed by '::' must be a class or namespace name

Can anyone help me with this please Thanks
