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. 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. Thus, our approach combines the cognitive abilities of humans with the computational accuracy of the machine to solve this problem. These simple cognitive tasks for humans are particularly difficult for automatic algorithms. Such extraction requires understanding of the components of the shape, their projections, and relations. We introduce an interactive technique for manipulating simple 3D shapes based on extracting them from a single photograph. The team behind it (Tao Chen, Zhe Zhu, Ariel Shamir, Shi-Min Hu and Daniel Cohe) wrote: 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 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. It takes three mouse strokes to generate a 3D component and each stroke defines one dimension of the component. 
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.
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. Scientists at Tel-Aviv University in Israel and Tsinghua University in Beijing have moved the cut-and-paste into the third dimension.
