Extracting 3D objects from images
If this is for real, it is very impressive. It is from a presentation at the SIGGRAPH conference, so I presume it is real... In the video below, some folks have come up with a technique for extracting 3D objects from 2D images. Not worrying about the fact that it is impossible (since there is no way to know what is on the far side of an object in a 2D image), they appear to have used a set of techniques from photo editing programs like Photoshop, combined with modeling techniques from programs like Blender to allow you to create three dimensional computer models of objects from two dimensional images. This technique is limited to symmetrical objects, but it certainly opens up exciting possibilities. The future is sure to be an exciting and interesting place.
