GOTURN not working after 3.4.1

[chrmertz]

System information (version)

works with:

• OpenCV => 3.4.1 does not work with later versions, I tested with:
  • OpenCV =>3.4.2 and 4.1.1
• Operating System / Platform => Ubuntu 18.04 installed with: sudo pip install opencv sudo pip install opencv-contribute (for version 4.1.1) and sudo pip install opencv==3.4.1.15 sudo pip install opencv-contribute==3.4.1.15 (for version 3.4.1) and in anaconda: conda install opencv (for version 3.4.2)

Detailed description

I ran the program goturnTracker.py which I got from https://www.learnopencv.com/goturn-deep-learning-based-object-tracking/

It gives different results when running with opencv 3.4.1 then when running later versions. I confirmed this with my own tracking program, it was tracking well wit opencv 3.4.1, but did give bad results with the later versions.

Steps to reproduce

follow the instructions in https://www.learnopencv.com/goturn-deep-learning-based-object-tracking/ and run "pythone3 goturnTracker.py" after installing different versions of opencv (3.4.1 to see it run correctly, later versions for running with problems.

Example of successful and unsuccessful tracking is shown in the two videos in the attached zip file.

I can confirm this. With newer versions of OpenCV, the tracker is not working as well as it used to.
