Image segmentation is the process by which objects are extracted from their surroundings in images. Segmentation in two dimensional images is a well-researched area, with both user-interactive and non-user-interactive tools to perform this function. While research has been done in three-dimensional image segmentation, few user-interactive tools exist that work directly in 3D. We present Live Me...

As modeling and visualization applications proliferate, there arises a need to simplify large polygonal models at interactive rates. We present a simplification algorithm suitable for interactive applications. The algorithm is fast and can guarantee displayable results within a given time limit. Results also have good quality. Inspired by splitting algorithms from vector quantization literature...

automatic analysis of human facial expressions is one of the challenging problems in machine vision systems. it has many applications in human-computer interactions such as, social signal processing, social robots, deceit detection, interactive video and behavior monitoring. in this paper, we develop a new method for automatic facial expression recognition based on facial muscle anatomy and hum...

Facial caricatures exaggerate key features to emphasize unique structural and personality traits. It is quite a challenge to retain the identity of the original person despite the exaggerations. We find that primitive shapes are well known for representing certain personality traits, in art and psychology literature. Unfortunately, current automated caricature generation techniques ignore the r...

Interactive narrative systems attempt to tell stories to players capable of changing the direction and/or outcome of the story. Despite the growing importance of multiplayer social experiences in games, little research has focused on multiplayer interactive narrative experiences. We performed a preliminary study to determine how human directors design and execute multiplayer interactive story e...

A tool for the interactive study of gravitational lensing is presented. Gravitational lensing is a known astrophysical phenomenon explained by means of the General Relativity Theory and it is nowadays the only scale independent method for measuring the mean matter density in the Universe. The gravitational lensing problem along with the associated physics is briefly described. The algorithm use...

We present an interactive algorithm to generate plausible trajectories and full-body crowd simulations. Our formulation is based on a novel two-way coupling between 2D multi-agent collision avoidance and high-DOF human motion synthesis. We present a collision-free navigation algorithm that takes into account human motion and biomechanics constraints to compute smooth trajectories. Furthermore, ...

COMIND is a tool for conceptual design of industrial products. It helps designers define and evaluate the initial design space by using search algorithms to generate sets of feasible solutions. Two algorithm visualization techniques, Kaleidoscope and Lattice, and one visualization of n-dimensional data, MAP, are used to externalize the machine’s problem solving strategies and the tradeoffs as a...
