A Measure For Spatial Dependency In Natural Stochastic Textures

Sabine Süsstrunk, Roberto Costantini, Gloria Menegaz

Random textures differ from natural textures because they lack structure. Structure is a concept that is difficult to formalize, however, we generally observe that it is associated to spatial dependency between adjacent pixels. Random textures, in fact, ar ...

Comparison between ray-tracing simulations and bi-directional transmission measurements on prismatic glazing

Marilyne Andersen, Jean-Louis Scartezzini

Evaluation of solar heat gain and daylight distribution through complex window and shading systems requires the determination of the bi-directional transmission distribution function (BTDF). Measurement of BTDF can be time-consuming, and inaccuracies are l ...

Automated Parameterization and Patching of Bifurcating Vessels

Recent developments in computational modeling of human arteries have opened the possibility of performing subject-specific analyses on increasingly larger numbers of subjects. This achievement will eventually lead to a better understanding of the role of g ...

Intraband spectroscopy of self-organized GaN/AlN quantum dots

Nicolas Grandjean

GaN/AlN quantum dots grown by molecular beam epitaxy either on silicon (111), sapphire or 6H-SiC (0001) substrate have been investigated using photoluminescence, cathodoluminescence, Fourier transform infrared spectroscopy and attenuated total reflection s ...

Avatar Markup Language

Daniel Thalmann, Anthony Guye-Vuillème

Synchronization of speech, facial expressions and body gestures is one of the most critical problems in realistic avatar animation in virtual environments. In this paper, we address this problem by proposing a new high-level animation language to describe ...

3D modeling of the human upper limb including the biomechanics of joints, muscles and soft tissues

The challenge in virtual human modeling is to achieve the representation of the main human characteristics with as much realism as possible. Such achievements would allow the simulation and/or analysis of many virtual situations involving humans. Simulatio ...

Automated body modeling from video sequences

Pascal Fua, Ralf Plänkers

Synthetic modeling of human bodies and the simulation of motion is a long-standing problem in animation and much work is involved before a near-realistic performance can be achieved. At present, it takes an experienced designer a very long time to build a ...

Displacements of the tibial tuberosity - Effects of the surgical parameters

Dominique Pioletti, Lalaonirina Rakotomanana Ravelonarivo, Pierre-François Leyvraz

A three-dimensional computer model is used, based on the finite element method, to investigate the effects of 1-, 1.5-, and 2-cm tibial tubercle elevations and of 0.5- and 1-cm medial displacements of the tuberosity performed with different bone shingles. ...

Real-time facial interaction

Daniel Thalmann

The human interface for computer graphics systems is evolving to involve a multimodal approach. It is now moving from keyboard operation to more natural modes of interaction using visual, audio and gestural means. This paper discusses real-time interaction ...
