Existing volume visualization techniques are rvpically applied to a three-dimensional grid. This presents some challenging problems in the visualization of environmental a!ata, These &ta often consist of unevenly distributed samples. Typically a two-step approach is used to visualize environmental &a. First the unevenly distributed sample data are modeled(More)
Virtual Reality (VR) and associated technologies are experiencing growing importance in medicine and surgery. VR demands fast and real time simulations. Finite element analysis can be used for cutting simulation; however, finite element analysis is computationally intensive and is unsuitable for real time applications involving cutting of a large amount of(More)
This paper presents the ASVC (Acquisition, Simulation, Visualization and Controller) framework for integrating heterogeneous virtual surgery modules. The framework extends the well-known MVC (Model-View-Controller) system architecture to make virtual surgery systems flexible and efficient. The framework can be used to construct stand-alone or server-client(More)
Motion deblurring is a knotty problem, especially when the photo is shot in a low lighting scene with a long exposure time or a strong reflected lighting scene. In this situation, partially saturated pixels violate the assumption of linear model and the recovered image contains severe ringing artifacts. In this paper, we proposed a novel two-layer images(More)
This short paper describes an ongoing NSF-funded project on enhancing science and engineering education using the latest technology. More specifically, the project aims at developing an interactive learning system with Microsoft Kinect and Unity3D game engine. This system promotes active, rather than passive, learning by employing embodied cognition with(More)
