Wow, this is really cool. Scientists at Tel-Aviv University in Israel and Tsinghua University in Beijing have moved the cut-and-paste into the third dimension. With just a few mouse clicks, a software can extract an 3D object out of a photograph and turns it into a 3D, editable creation.

Scheduled to be demonstrated at Siggraph Asia 2013 in November, the software "3-Sweep" lets the user to select an object in a photo by swiping along them with a mouse cursor. It takes three mouse strokes to generate a 3D component and each stroke defines one dimension of the component. The computer reshapes the component to fit the image of the object in the photograph as well as to satisfy various inferred geometric constraints imposed by its global 3D structure.

Once the 3D object has been extracted, it can be quickly edited, rotated, adjusted and placed back into photos or 3D scenes, permitting object-driven photo editing tasks which are impossible to perform in image-space.

The team behind it (Tao Chen, Zhe Zhu, Ariel Shamir, Shi-Min Hu and Daniel Cohe) wrote:

We introduce an interactive technique for manipulating simple 3D shapes based on extracting them from a single photograph. Such extraction requires understanding of the components of the shape, their projections, and relations. These simple cognitive tasks for humans are particularly difficult for automatic algorithms. Thus, our approach combines the cognitive abilities of humans with the computational accuracy of the machine to solve this problem. Our technique provides the user the means to quickly create editable 3D parts— human assistance implicitly segments a complex object into its components, and positions them in space.

In the video below the team shows off what the software is potentially capable of, and also describes some instances in which the algorithm would not work, including when there is a non-ideal perspective, or when an object has a fuzzy edge.

This is really an impressive work.

Thanks to Nancy for the tip.

i say fags for not making on online demo at least and claiming software but not giving for free or selling it. smells like bulshtii.

Why can't the developers give us a trial version of this program. Would be great to try it out.

How does the software know what the background looks like, when the object is moved?

I have a stuffed animal that I would like to be able to create a 3D object of and (potentially) animate into a short cartoon-like short subject. I wonder if this software would work, since the derived object can be edited. What do you think?

So were to get the software? +1
