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."

I think the most interesting part of computer vision is that which deals with passive sensing, such as this work. It senses the electromagnetic radiation that comes from our sun, or moon, or man-made sources. By using the same spectrum that our eyes use it should be able to get a qualitative understanding of the world similar to what humans can achieve.
Also, as humans we've built the world to be visually interpreted at the EM frequencies that we sense. This means our signs are readable in those frequencies, our indoor lighting works in those frequencies, etc... By sensing in those frequencies you make sure you don't miss anything that humans can see.

Same reason you can't waltz into the mall security office and ask for the license plate number of the person that scraped against the side of your car when they were backing out. The minimum pixel of a 320x200 picture is much larger than the minimum pixel size on 1920x1080. And since a pixel is the smallest unit of color you can get, there's going to be very little zooming you can do on such a shitty picture to begin with.
That and the waltz is usually banned at malls.
