face expression recognition is useful for designing new interactive devices offering the possibility of new ways for human to interact with computer systems. in this paper we develop a facial expressions analysis and synthesis system. the analysis part of the system is based on the facial features extracted from facial feature points (ffp) in frontal image sequences. selected facial feature poi...

We propose a simulation framework to simulate the computed tomography acquisition process. It includes five components: anatomic data, respiration modelling, automatic parametrisation, X-ray simulation, and tomography reconstruction. It is used to generate motion artefacts in reconstructed CT volumes. Our framework can be used to evaluate CT reconstruction algorithm with motion artefact correct...

This paper presents the application of rigid body simulation for assembly tasks in a virtual environment and the extension of this system to the real-time simulation of deformable cables. Presently our virtual reality tools evaluate virtual prototypes based on CAD models of the design department. We motivate the need for deformable objects, especially cables, by practical examples and explain o...
