Remember the /. effect, I'd be amazed if the site in question isn't overloaded for at least a day.

An anonymous reader writes to tell us that Stanford has a new website that not only shows you how cool their new 3-d modeling system is, but actually allows you to give it a try with your own photos. The system can take a 2-d still image and estimate a detailed 3-d structure which you can navigate. "For each small homogeneous patch in the image, we use a Markov Random Field (MRF) to infer a set of "plane parameters" that capture both the 3-d location and 3-d orientation of the patch. The MRF, trained via supervised learning, models both image depth cues as well as the relationships between different parts of the image. Other than assuming that the environment is made up of a number of small planes, our model makes no explicit assumptions about the structure of the scene; this enables the algorithm to capture much more detailed 3-d structure than does prior art (such as Saxena et al., 2005, Delage et al., 2005, and Hoiem et el., 2005), and also give a much richer experience in the 3-d flythroughs created using image-based rendering, even for scenes with significant non-vertical structure."

I just tested it, not responding.

Edit: Mod's, feel free to move this thread. Not that you need my permission. ;)

Edit 2: Crap, I should have read the FAQ, sorry. So either delete or move it, I guess.

A quick search on youtube revealed this video [youtube.com] which seems to be of the software in question.

The summary mentions prior work by Hoiem at CMU (slashdotted here [slashdot.org]), a video of which can be also seen on Youtube. [youtube.com]

I'm not sure I'm very impressed by the Stanford videos. In the few examples of non-vertical surfaces, you can see quite a few artifacts.

Medium cool imo. I think the idea has a definite future.
