OpenCV 3 Tracker won't work after reinitialization

Question

I have issue using OpenCV 3 tracking module for tracking. It behaves same, either I use interface class (cv::Tracker) or class with implementation (like cv::TrackerMedianFlo

Answer 1

I ran into the same problem and here's my solution: Open the file in opencv_contrib/modules/tracking/src/tracker.cpp and apply the following changes:

-  if( isInit )
+  /*if( isInit )
   {
     return false;
   }
+  */

I recompiled opencv3 and reinstalled it. That fixed it for me. I think they did not want people to reinitialize the tracker for some reason. I am not sure why?
