It involves a mouse and a big wheel. - jstohler, on 10/12/2007, -10/+54That's badass.
- evanstapler, on 10/12/2007, -4/+43This brings pornography into a whole new DIMMENSION!
- nights0223, on 10/12/2007, -1/+28Yes, it was this one. I specifically remember that train animation.

README for Automatic Photo Pop-up
The photo pop-up algorithm consists of two main stages: estimating a rough labeling of the geometry of the image and using that geometric information to construct a 3D model. The first of these stages tends to be fairly accurate and results in probability maps for each of three main geometric classes (ground, vertical, sky) and five subclasses of vertical (planar facing left/right/center, porous, and solid). The second stage of constructing the model works in limited scenarios. If you can imagine constructing a pop-up of the image by making a few straight cuts and a few straight folds, then the algorithm might be successful; otherwise it is likely to give some very rough approximation of the scene.
Details on how our method works can be found in our SIGGRAPH, ICCV, and IJCV (draft) papers online at www.cs.cmu.edu/~dhoiem/publications/. This online version is from the ICCV paper, which may produce slightly different results than the SIGGRAPH or IJCV versions. Also, because the algorithm is random, it is possible to get slightly different results on different trials of the same image.
Input:
One color image. The algorithm has been trained on real outdoor images taken from the ground, but it is sometimes fun to see if it works on paintings, indoor images, and strange viewpoints.
Output:
The primary output of the algorithm is a labeling into geometric classes with associated probability maps:
*.l.jpg: a labeling of the image (green=support, red=vertical, blue=sky ; arrows indicate planar directions, 'O' for porous, 'X' for solid)
*.v000.pgm: probability of support (e.g. ground) given image
*.v090.pgm: probability of vertical (i.e., anything sticking out of the ground) given image
*.vsky.pgm: probability of sky given image
*.h045.pgm: probability of planar (e.g. wall), facing left given vertical, image
*.h090.pgm: probability of planar, facing center given vertical, image
*.h135.pgm: probability of planar, facing right given vertical, image
*.hpor.pgm: probability of porous surface (e.g. tree leaves) given vertical, image
*.hsol.pgm: probability of solid non-planar surface (e.g. a person) given vertical, image
The secondary output of the algorithm is the photo pop-up model:
*.wrl: VRML model (requires VRML viewer such as Cortona to view)
*.png: texture maps for 3D model
Yup I dont get it either... - Oly701, on 10/12/2007, -0/+22Ha, surely you jest.
Every inventor and entrepreneur knows the easiest way to a successful product is make it somehow useful to the porn industry (and of course, don't get involved in land wars in Asia). - Aliarse, on 10/12/2007, -1/+23Silicone.

- niradg, on 10/12/2007, -2/+18people still use VRML?
- troymcdavis, on 10/12/2007, -0/+15@ hdtvdust
Can anything else explain the ubiquity of high-speed internet? - BrianOl, on 10/12/2007, -0/+14Yup, here it is: http://www.digg.com/software/Create_3D_Images_out_of_2D_Pictures
They have links to the software as free downloads as long as its not for commercial usage. - Flashman, on 10/12/2007, -0/+8"The 3D image is constructed in Virtual Reality Modeling Language (VRML) format, meaning you currently need a VRML reader to see it (future browsers will likely build this functionality in)."
Hahaha - 13 years late, I think. - mash8591, on 10/12/2007, -0/+7I swear I have seen that train and that house somwhere before...
- Heembo, on 10/12/2007, -1/+7hdtvdust : The gutenberg printing press and every other media device since then know to man, you idiot!
- cenithx, on 10/12/2007, -1/+7I was just going to comment.. I thought VRML was dead? When it first came out I played with it for a bit, relatively excited about it.. but it seemed to fizzle out and vanish completely..
- zizzy, on 10/12/2007, -0/+5A bunch of examples:
http://www.freewebs.com/fotowoosh/demo.html - dacheetah, on 10/12/2007, -0/+5lol yeah. I remember playing with VRML back in early high school a decade ago, when they were saying it'll be implemented into browers as a default soon.
It's not a bad markup language, but it's also basically dead, and I don't think we'll see it as a default option in many browsers. - Aliarse, on 10/12/2007, -3/+5That was just a demonstration. This one is announcing that everyone will be able to have a go at using it.
- TimDigg, on 10/12/2007, -0/+2Funny because I was just about to move to Cali....ironic because someone was just telling me yesterday "you underestimate the talents in maryland"....
- morphie, on 10/12/2007, -0/+2So, come up with a link older than a year then. We all know this have been on digg before. The thing is, now it becomes available to all online.
- pbgswd, on 10/12/2007, -1/+3vrml is dead. I really loved stuff I saw in vrml, but its dead dead dead now.
- grogan, on 10/12/2007, -1/+3Did you actually read the article? This is using heuristics to make a 3D model of the scene depicted by a photo. The zooming and panning is just a way to show that off.
From http://en.wikipedia.org/wiki/Ken_Burns_Effect :
The Ken Burns Effect, made famous by American documentarian Ken Burns, refers to a technique of embedding still photographs in motion pictures, displayed with slow zooming and panning effects, and fading transitions between them. - nodnarb24, on 10/12/2007, -0/+2If you are interested in how they did it, you can read their paper on it here: http://www.cs.cmu.edu/~dhoiem/publications/popup.pdf
It can work on any image but only really works well on outdoor images, especially of man-made structures. The paper shows some of their failure images as well. - swordedge, on 10/12/2007, -0/+2seen something like this before. Not really 3D, just fancy processing of a 2D picture. Still nice though
- mookieXL, on 10/12/2007, -0/+1moft is right. Canoma (and few other programs) can do same thing and results look much better. (But it requires some manual editing)
- ipodman715, on 10/12/2007, -1/+2Wow, something from Maryland! Go Maryland! :P
- TimDigg, on 10/12/2007, -1/+2Dugg for "Maryland-Based"
- harrymcwealth, on 10/12/2007, -0/+1When I first saw it, I thought it would fill in the unknown area behind (too). You know kind of like a human. If you cover half a letter, they figure out what the rest is. Now that would be amazing.
- kutza, on 10/12/2007, -0/+1Hrmm... Trying to install the cortata plugin on firefox in vista, but it's giving me an error 202 (access denied). Anyone have any clue to bypass this?
- digitalArtform, on 10/12/2007, -0/+1I do mine like this:

- shervster, on 10/12/2007, -0/+1remember this works from just one single picture. the algorithm for indoor pictures is coming. we will widgetize this so people can view this through flash and publish and share their 3D pictures anywhere without ever using VRML. think about the cool things you could do with this if we mash it up with google maps or google earth and allow you to see the street scenes at the ground level from single pictures taken at the ground level. mathematically this was impossible. it really takes cues from how the human brain infers a scene and sees it in 3D.
- motters, on 10/12/2007, -0/+1I know the inner details of how this system works, and it's really not as impressive as the animations might suggest. The 3D photo-popup effect is *very* approximate and only works - to a degree - under certain limiting circumstances. It certainly doesn't work with just any old photo. If I was a venture capitalist interested in 3D photo technology I'd put my money into something like photosynth rather than the CMU photo-popup system.
- LordLandon, on 10/12/2007, -0/+1@quickgold
when you look at something with your eyes, you have two perspectives, due to two eyes. your brain uses the differences between the two perspectives to estimate depth
in the case of a picture, you only have one perspective and depth cannot be estimated as easily. - ConceptJunkie, on 10/12/2007, -0/+1Really? I never saw anything in VRML that didn't look like state-of-the-art 3D from 1993, i.e., like crap.
- maiku00, on 10/12/2007, -3/+4VERY cool. You could do this to some pretty neat things. I wonder what some of the 9/11 Photos would look like?
- shortarabguy, on 10/12/2007, -0/+1It looks like this has been having trouble from the start... Is this thing even working?
- b04155, on 10/12/2007, -0/+1I'm just as impressed at the last time I saw this, ie no improvement. It's not a dupe I'm referring to rather the work finally moved from the lab into a real world app. However, they're still demo-ing the SAME pictures that were seen last time.
- nick2, on 10/12/2007, -0/+1This looks awesome!
- kohan69, on 10/12/2007, -0/+1@maya 3d mapping now THAT is really cool.
This 3D picture thing would be useful if it at least exported a picture into a 3ds model + texture - FastZ, on 10/12/2007, -0/+1Why must they delete the sky in each of the pictures? Can they not use that in the 3d version?
- Kitsune818, on 10/12/2007, -0/+1This isn't really 3D at all, its more of a perspective trick. The farther you get from the original point of view, the more the objects will be distorted. Imagine if you could move into that picture of the train a bit, then turn and look back.. the texture on the 3D model would have the angles all wrong.
Remember that guy who draws "3D" images on the sidewalk with chalk? But it only works if you look at it just right, and with only one eye. If you look at it from any other angle it's hard to tell what it's supposed to be. It also looks really impressive in photos because there is only a single POV, but with two human eyes in person it doesn't look nearly 3D at all (Although it's pretty cool).
This is just a passing thing, there isn't enough information there to do much more than those little panning demos they've already shown us. - dpoehls, on 10/12/2007, -0/+1@recurso
Ha! - Cyberdactyl, on 10/12/2007, -0/+1Google Sketchup has had that as an imbedded function called photomatch, then simply exporting a avi.
- omeomi, on 10/12/2007, -1/+1I think it's funny that the article says "you currently need a VRML reader to see it (future browsers will likely build this functionality in)". Future browsers? Netscape 4 would parse VRML...if current browsers don't, it's because VRML sucks, and nobody wanted it...
- cavar, on 10/12/2007, -0/+0I can do this with Canoma.
