Our work draws inspiration on how computers can work with shapes to help humans sketch, locate objects, search on local features, manipulate and change, analyze, classify millions of objects, and bring order in a disordered environment. Read an article in discovery science to get a flavor for our research.

Origami-inspired design method merges engineering, art
In this paper we present our initial prototypical explorations as well as the associated transformative design concept called Kaleidogami. This method is used for developing spatial objects that can be flattened, folded and reconfigured. We develop the metaphor and concept for a basic structural unit (BSU) such as using tetrahedral, cuboidal, prismatic, and pyramidal units to enable new forms of 3D folding. The fabrication is done using a single flat sheet of foldable substrate in 2D. We explore the diversity of structural polyhedral sculptures and movable constructs in a hierarchical architecture. More artistic constructions are contextualized with a Kaleido-Tangram like integration.

Genius of Einstein, Fourier key to new humanlike computer vision
Two new techniques for computer-vision technology mimic how humans perceive three-dimensional shapes by instantly recognizing objects no matter how they are twisted or bent, an advance that could help machines see more like people. (source: Purdue News Service)

Now, Doodle it...
Mumbai News: Forget word-based search engines. Cutting-edge algorithm can hunt through online catalogues using only a sketch; researchers say technology could become mainstream so consumers could just draw to find an exact match.
Professor Ramani is selected to receive the Thomas French Award from The Ohio State University
The Thomas French Achievement Award is presented to alumni who have distinguished themselves as educators. Thomas French, an 1895 graduate of The Ohio State University, served as a professor of engineering drawing at his Alma Mater and introduced new teaching methods and authored a popular textbook. He was awarded the Lamme Medal in 1943

Press Release 06-035 "Doodle Search"
Working with support from the National Science Foundation's Small Business Innovation Research (SBIR) program, Imaginestics, a company located in West Lafayette, Ind., has created 3D-Seek: a new kind of search engine that lets users find items in an online catalog without ever needing to know the items' names, part numbers or keywords. Thanks to a major advance in practical pattern recognition, all the user needs is a freehand sketch--a doodle.
