While the results are not true 3D images they are still very impressive. I tested the script with two images that I took last summer, one from the North Sea [link] and one from my trip to Berlin showing Berlin Cathedral [link].

No user input at all other than selecting an image from Flickr or your computer and tagging it is required. The script is transforming the image automatically one after the other. You receive a message about your queue position and will receive an email once the transformation finishes.

Users can then zoom in and out of the image, turn, move forward, backward and up and down using the cursor keys. Adobe Shockwave is required for the script to work.

How does it work ?

Our software uses a breakthrough technology in machine learning. It estimates depths from the single image by using our monocular vision algorithm, developed in 2005. It captures a variety of monocular cues and learns the relations between different parts of the image using a machine learning technique called Markov Random Field (MRF). Our algorithm first divides the image into small patches and analyzes them at multiple scales to estimate each of the patches’ 3-d location and 3-d orientation. More details could be found here.

Feel free to share your images.

Seadragon is basically a way to navigate seamlessly through a very large amount of image data. He was giving three examples at the presentation.

First he introduced a 300 Megapixel image, then that he was able to zoom into a complete book and lastly that it was possible to create new types of ads that would allow to zoom in and reveal details that would not be possible otherwise.

Photosynth on the other hand can be seen as a technology that takes lots of images of an object and combine them to form 3D models of that image. His example this time was Notre Dame. Images were taken from Flickr and you could see how they were combined to create the 3D image. Take a look at the video, it is really incredible.
