Dynamic Storyboard Generation in an Engine-based Virtual Environment for Video Production
Amateurs working on mini-films and short-form videos usually spend lots of
time and effort on the multi-round complicated process of setting and adjusting
scenes, plots, and cameras to deliver satisfying video shots. We present
Virtual Dynamic Storyboard (VDS) to allow users storyboarding shots in virtual
environments, where the filming staff can easily test the settings of shots
before the actual filming. VDS runs on a "propose-simulate-discriminate" mode:
Given a formatted story script and a camera script as input, it generates
several character animation and camera movement proposals following predefined
story and cinematic rules to allow an off-the-shelf simulation engine to render
videos. To pick up the top-quality dynamic storyboard from the candidates, we
equip it with a shot ranking discriminator based on shot quality criteria
learned from professional manual-created data. VDS is comprehensively validated
via extensive experiments and user studies, demonstrating its efficiency,
effectiveness, and great potential in assisting amateur video production.Comment: Project page: https://virtualfilmstudio.github.io
Expressing social attitudes in virtual agents for social training games
The use of virtual agents in social coaching has increased rapidly in the
last decade. In order to train the user in different situations than can occur
in real life, the virtual agent should be able to express different social
attitudes. In this paper, we propose a model of social attitudes that enables a
virtual agent to reason on the appropriate social attitude to express during
the interaction with a user given the course of the interaction, but also the
emotions, mood and personality of the agent. Moreover, the model enables the
virtual agent to display its social attitude through its non-verbal behaviour.
The proposed model has been developed in the context of job interview
simulation. The methodology used to develop such a model combined a theoretical
and an empirical approach. Indeed, the model is based both on the literature in
Human and Social Sciences on social attitudes but also on the analysis of an
audiovisual corpus of job interviews and on post-hoc interviews with the
recruiters on their expressed attitudes during the job interview
06241 Abstracts Collection -- Human Motion - Understanding, Modeling, Capture and Animation. 13th Workshop
From 11.06.06 to 16.06.06, the Dagstuhl Seminar 06241 ``Human Motion - Understanding, Modeling, Capture and Animation. 13th Workshop "Theoretical Foundations of Computer Vision"\u27\u27 was held
in the International Conference and Research Center (IBFI),
Schloss Dagstuhl.
During the seminar, several participants presented their current
research, and ongoing work and open problems were discussed. Abstracts of
the presentations given during the seminar as well as abstracts of
seminar results and ideas are put together in this paper. The first section
describes the seminar topics and goals in general
Fast Complementary Dynamics via Skinning Eigenmodes
We propose a reduced-space elasto-dynamic solver that is well suited for
augmenting rigged character animations with secondary motion. At the core of
our method is a novel deformation subspace based on Linear Blend Skinning that
overcomes many of the shortcomings prior subspace methods face. Our skinning
subspace is parameterized entirely by a set of scalar weights, which we can
obtain through a small, material-aware and rig-sensitive generalized eigenvalue
problem. The resulting subspace can easily capture rotational motion and
guarantees that the resulting simulation is rotation equivariant. We further
propose a simple local-global solver for linear co-rotational elasticity and
propose a clustering method to aggregate per-tetrahedra non-linear energetic
quantities. The result is a compact simulation that is fully decoupled from the
complexity of the mesh.Comment: 20 pages, 24 figure
Using VCR to Support Different Styles and Types of Group Collaborations in Virtual Universities
[[abstract]]To support many different group activities such as computer and network based meeting, seminar, conference, tele-lecturing, group project, team work, student instruction and club in a virtual university, a general framework based on a room metaphor or model is used to develop a desktop groupware system, called virtual collaboration room (VCR) that enables teachers and students to flexibly and naturally conduct their collaborative teaching/learning/working over the Internet without constraints on collaboration type, working style, group scale and system platform. As important component in our integrated educational system, University21, the VCR is discussed how to be employed and managed in a virtual university. With the use of Java applets for system implementations, users can enter the VCR from any standard Java enabled Web browser. VCR consists of user panel, object cabinet, object panel, a variety of objects in workspace, workspace panel. An object in VCR has a life cycle from birth, alive to death, and attributes such as owner, state, access mode, handler, and persistence. To further improve the quality of collaborations, natural object control and rich awareness function are fully supported.[[notice]]補ćŁĺ®Ś
