"On Using Raw MPEG Motion Vectors To Determine Global Camera Motion"

Have any of you seen this paper?

http://www.hpl.hp.com/techreports/97/HPL-97-102.pdf

It basically does what I need to do in part of my project. You think OF could have anyway of reading the bitstream of an MPEG and pulling the scene change and computed motion vectors out? This would save me time and computation from doing it as I am now.
