Model-based tracking / Edge-Based tracking [closed]

edit

I have a question about the concept behind POSIT, is it the same idea as in model-based / edge-based tracking tracking like these:

Conics Tracking (CT)

• http://www.youtube.com/watch?v=D6xeXcgl_Qo
• http://www.aist-nara.ac.jp/~takafumi-t/pdf/SVR12_oikawa.pdf

So there are also Sparse Line Tracking (SLT) and Dense Line Tracking (DLT)

And there is also http://www.cc.gatech.edu/~cchoi/textureless_tracking_files/Choi12iros_2d.pdf ( http://www.youtube.com/watch?v=UJtpBxdDVDU ) where i don't know what approach they are using.

So does POSIT do the same? I couldn't find information if there is already any existing implementation in OpenCV for edge based tracking and I think I would not be able to implement it based on the existing papers ;) So i thought i should ask if POSIT can be used in a similar way or if I should do something else.
