Interpolating 360 degree Images out of only 8 images that are 45 degrees apart

Hi,

Sony has demonstrated a very nice technology in Siggraph 2010 where an object can be displayed on a "round LCD" so it could be visible from all directions in 3D without the use of special glasses.

This is very nice but in the demonstration movie I saw something that caught my eye. In order to display a 360 degree image they have to generate 360 images (one degree apart) of the object they want to show. Sony are able to interpolate 360 images from only 8 (45 degrees apart).

I was looking allot for such mothod/algorithem and I would be very happy to know if there is a paper on the subject. Anyone?

Thanks.

Why do you look at their Siggraph paper ? You should find explanation and pointers to other papers with similar work.

That was my question, if anybody know of such paper (academic) or algorithm/method.

I try but didn't find their paper. The way I would do it : build a 3D model of the object from these 8 cameras and then project the 3D point on any plane (i.e. camera) you want. Since they are showing it in 3D they will anyway need the 3D model.

I thought about that for quite a while. It is not so easy building a 3D module and then project it. The images doesn't look very synthetic and real enough. In Sony's presentation, their images look very very good, no chance it is 3D based.
