DVD Player Displays 2D Movies in 3D
Anonymous Writer writes "A company called Dynamic Digital Depth that wants to bring 3D television and movies to the mainstream claims to have developed a system that allows you to watch current 2D DVDs in 3D.
They claim the TriDef DVD Player uses image analysis methods, developed by the company for their 3D content conversion service, to convert 2D video to 3D in real-time based on 3D depth cues in the original movie.
It is the same company that produced the TriDef Movie Player software for the Sharp Actius R3D3 autostereo display notebook.

The principle seems straight forward enough. You don't have enough 3D info in a single frame, but you have lots of frames. So as objects move, or the camera pans, you can tell by their apparent positional shift how far from the observer they are. Assuming the software can recognize and track some basic objects, it can make reasonable inferences about their depth into the scene. How it then displays the depth is another issue.
There's plenty of info to construct a 3D-image. There's just not enough to construct the 3D-image.
Part of the bizplan likely involves consumers not caring.
Seeing bad movies only encourages them. Watch responsibly
Not really that reasonable. If you look at the results of current optical flow and disparity estimation algorithms, they're really not that great. Discontinuities of the image (edges) are a huge problem, as is the whole top-down/bottom-up/gestalt-ordeal, and these have not been solved in any satisfactory manner.
To reconstruct the 3D scene generating the 2D images is effectively to solve vision, in its entirety. In real time, no less. So I would guess that they're doing something quite simple. I'd love to see it, but the information on the site is quite scarce. I'm just hoping that someone is not manually pulling the strings behind the scenes.
