(Harsh) Tracking in Video using a Time Series Transformation Learning approach


Hello everyone.

This presentation will be based on this CVPR 2005 paper. You really don't need to read the paper (unless you badly want to!). Besides, I will be using slightly different notation.

There's a sizeable amount of mathematics involved. Before reading this paper, I had to revise some linear algebra and learn about Reproducing Kernel Hilbert Spaces {RKHS} (functional analysis). I suppose most of you if not all of you, are already aware of these concepts.

However, if any of you wish to have a refresher of this material, here are some excellent resources (and very small documents too):

Functional Analysis > do go through this if terms like "complete space", "Banach space", "Hilbert space of functions" etc. seem new.

Linear Algebra > you can read this if you find some terminology in the Functional Analysis document seen-before-but-quite-a-while-ago.

Finally, I am hoping that I will be able to devote minimal time to explaining what an RKHS is. Here's a document that explains it beautifully...only the first few pages are actually needed for understanding RKHS (pages 14-17 mainly)

Wahba - An Intro to Model Building with RKHS

If this seems too much, you can alternatively go through my slides on RKHS (these are also on the actual presentation).

In any case, if you wish I can go over the RKHS slides during the presentation (at the moment though, I'm not planning to).
