Re: Draw polygons on moving cars in video

Hi Terry

I have to say I'm not an expert in this area, but found this link a
while ago.  "MPEG-7 Description for Scalable Video Reconstruction"
http://lts1pc19.epfl.ch/repository/Steiger2004_740.pdf it might give
you some information about area description.

I don't know if you have to do all of it with html+time, smil,? I
guess  it's quite time consuming to edit all the shapes in all frames.
I don't know if you have a tool do extract all the x,y information?

Well I assume you want to create a layer for some kind of
hotspot(link) with this? If it's just the polygon around it, why don't
you do it with some postproduction tool. I guess they have some
functionality to follow object whereas I can't confirm this, cause I
never personally worked with one of them.

If you found something that will work for you, post it to the list.
Well at least I'm also interested in the solution. I think the area is
quite interesting for advertising possibilities,... with
html+smile,...
