Tracking issues

Hi all,

after a few years I now got my hands on vvvv again.
Much happened within vvvv and I’m really amazed by
the freeframe tracking possibilites.
So i tried to make my own tracking patch. My intention
was to let an *.x object track an object in the video.
This is basicly working, but there are a few glitches.

The more I go to the sides of the video with the object
to be tracked, the less accurate are the results I get.
Also the object which tracks the one in the video is
sometimes flipping over 180°. I can’t explain to myself
why this is. It would be nice, if anybody could help.

I uploaded a video of my tracking results. I also added
comments to the video to show where the Problem is.

I also attached the patch. Thx in advance. :)
