Stanford's New Website Converts Your Photos to 3D 156
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."

Wow. That was fast.

Could this type of technology be used for robots to allow them to identify what the 3d layout of the world around them is?
Some (most?) robots already use dual cameras for true depth perception.

Microsoft does invest a lot of money in research. But what they are spending pales in comparison to all the work by other people that they are building on.

I'm sorry to say that us geeks have been usurped by young hipsters in the website-disabling stakes. This site has not been slashdotted, it has been YouTubed. Someone at Stanford has been uploading videos of this to YouTube and inviting the plebs to go to their site before us. How ungrateful. The swines. Harumph.
HAL.

Yes, the website was slash-dotted.....
We plan to have it up again at: http://make3d.stanford.edu/ [stanford.edu]
(Slashdot brought the whole Stanford AI lab servers down: http://ai.stanford.edu/ [stanford.edu]
Meanwhile, please see:
