In part 5 of the Motion Warp Tracking Series, you take on a difficult tracking shot where things either get in the way or there is too much pixel motion that affects the motion vectors analysis.

Basically you will track a tattoo to a street musician’s arm but his knee gets in the way and there is a lot of activity behind him.

Using a series of suggested techniques, you can take on these tracking challenges and generate a good motion vectors map for the correct tracking and distortions.
