A Hierarchical Keyframe User Interface for Browsing Video over the Internet

Daniel Gatica-Perez, Jean-Marc Odobez

We present an interactive content-based video browser allowing fast, non linear and hierarchical navigation of video over the Internet through multiple levels of key-frames that provide a visual summary of video content. Our method is based on an XML frame ...

Specifying MPEG-4 body behaviors

Daniel Thalmann, Anthony Guye-Vuillème

The MPEG-4 standard specifies a set of low-level animation parameters for body animation, but does not provide any high-level functionality for the control of avatars or embodied agents. In this paper we discuss the required features for a script format al ...

Construction of animation models out of captured data

Daniel Thalmann

This article describes a method of constructing parametric models out of captured motion and skeleton data. Casting the problem as scattered data interpolation, our work is based on a multi-step approximation for the interpolation function with motion data ...

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 ...

Steganography for Three-Dimensional Polygonal Meshes

Touradj Ebrahimi, Nicolas Aspert, Elisa Drelie Gelasca

This paper proposes a method to embed information into a 3D model represented by a polygonal mesh. The approach used consists in slightly changing the position of the vertices, in uencing the length of approximation of the normals to the surface. This tech ...

Interactive modeling of the human musculature

Daniel Thalmann, Amaury Aubel

In this paper, we extend our previous work (Proc. Computer Animation and Simulation, pp. 125-135, Aug. 2000) and propose a muscle model that is suitable for computer graphics based on physiological and anatomical considerations. Muscle motion and deformati ...

Using skeleton-based tracking to increase the reliability of optical motion capture

Daniel Thalmann, Pascal Fua, Ronan Boulic, Lorna Herda, Ralf Plänkers

Optical motion capture provides an impressive ability to replicate gestures. However, even with a highly professional system there are many instances where crucial markers are occluded or when the algorithm confuses the trajectory of one marker with that o ...

Inverse kinematics techniques of the interactive posture control of articulated figures

The context of this thesis is the interactive manipulation of complex articulated figures by means of geometric constraints (here called tasks), for the purpose of posture control and design. The goal is to determine a posture satisfying a set of prescribe ...

Human shoulder modeling including scapulo-thoracic constraint and joint sinus cones

Daniel Thalmann

In virtual human modeling, the shoulder is usually composed of clavicular, scapular and arm segments related by rotational joints. Although the model is improved, the realistic animation of the shoulder is hardly achieved. This is due to the fact that it i ...

Kinematic control of the mass properties of redundant articulated bodies

Ronan Boulic

In this paper we show how the mass properties of an articulated body, such as its center of mass and its moments of inertia, may be manipulated like any conventional end effector, with well-known iterative, numerical techniques. Within our interactive simu ...
