We employ the new primitive of non-interactive zero-sharing to realize efficiently and privately various “distributed decision making” procedures. Our methodology emphasizes non-interactiveness and universal verifiability. Non-interactiveness suggests that there is no need for bilateral communication between the active participants; instead decision making is achieved by unilateral communicatio...

We present an interactive image and volume denoising and segmentation tool, that allows the use of state of the art algorithms based on the concept of total variation (TV) to be applied to 2D and 3D grey and color value data. Our aim is to provide a research tool for experimenting with TV related methods to the medical image analysis community. Our implementation supports the classic ROF and TV...

When recovering and maintaining the architectures of software systems, effective visual presentations are essential for grasping the concepts and constructs involved. There exist several reverse engineering tools that provide visualizations of architectural information. The tools usually offer a set of views allowing interactive navigation of the architectural information in some predefined way...

Topics in speech and hearing are well-suited to demonstrations using media other than the printed word. Currently, educators rely largely on passive formats such as the CD collections for general auditory psychophysics [6], auditory scene analysis [2] and cochlear damage [10]. Progress in programming tools and cheap, multimedia hardware now presents the potential to go much further. The interac...

For demonstration of animal experiments to undergraduate students of medical and paramedical faculties, a large number of animals are sacrificed every year. Such demonstrations can be humanely presented using computer simulations rather than experimental animals. Considering the necessity of such computer assisted learning tool to reduce/ replace the animal use and to refine the demonstrations ...

Interactive exercise assistants support students in practicing exercises, and acquiring procedural skills. Many mathematical topics can be practiced in such assistants. Ideally, an interactive exercise assistant not only validates final answers, but also comments on intermediate steps submitted by a student, provides hints on how to proceed, and presents worked-out examples. For these purposes,...

Providing real-time, interactive immersive surgical training has been a key research area in telemedicine. Earlier approaches have mainly adopted videotaped training that can only show imagery from a fixed view point. Recent advances on commodity 3D imaging have enabled a new paradigm for immersive surgical training by acquiring nearly complete 3D reconstructions of actual surgical procedures. ...

Historical maps contain rich cartographic information, such as road networks, but this information is “locked” in images and inaccessible to a geographic information system (GIS). Manual map digitization requires intensive user effort and cannot handle a large number of maps. Previous approaches for automatic map processing generally require expert knowledge in order to fine-tune parameters of ...

Abstract Invasive techniques such as venipuncture are painful procedures causing stress and anxiety, both in pediatric patients their carers. For this reason, efforts being made to develop mitigating strategies for the patient’s pain anxiety during performance. To analyze evaluate effectiveness of use Virtual Reality distraction a measure reduction parents. In addition, effects two modes (passi...
