Focusing on specific domains, most traditional simulation systems have features of standalone-centralized running mode, weak interoperability with external simulation systems, difficult reusability of system components. With the technical development of the distributed simulation, the inspiration of developing reusable simulation model components satisfying the needs of simulation systems or environments...
An effective video coding should not only remove statistical redundancy but also take into account the characteristic of human visual system. Just noticeable difference (JND) represents the maximum distortion that cannot be perceived in a suitable viewing condition. In this paper, we introduce a foveated JND model combined with visual attention model. Though moving object always attracts viewer's...
Evaluation of the outcome (end-product) of surgical procedures carried out in virtual reality environments is an essential part of simulation-based surgical training. Automated end-product assessment can be carried out by performance classifiers built from a set of expert performances. When applied to temporal bone surgery simulation, these classifiers can evaluate performance on the bone specimen...
