A Constraint-Based Approach to Visual Speech for a Mexican-Spanish Talking Head

Oscar Martinez Lazalde, Steve Maddock, Michael Meredith
2008 International Journal of Computer Games Technology  
We describe an approach to such pose-based interpolation that deals with coarticulation using a constraint-based technique.  ...  A common approach to produce visual speech is to interpolate the parameters describing a sequence of mouth shapes, known as visemes, where a viseme corresponds to a phoneme in an utterance.  ...  ACKNOWLEDGMENTS The authors would like to thank Miguel Salas and Jorge Arroyo. They also like to express their thanks to CONACYT.  ...

Time-constrained Animation Rendering on Desktop Grids [article]

Vibhor Aggarwal, Kurt Debattista, Thomas Bashford-Rogers, Alan Chalmers
2012 Eurographics Symposium on Parallel Graphics and Visualization  
This paper presents a novel fault-tolerant rendering algorithm for generating high-fidelity animations in a user-defined time-constraint.  ...  A naive approach to employing desktop grids for rendering animations could lead to potential inconsistencies in the quality of the rendered animation as the available computational performance fluctuates  ...  Acknowledgements The authors wish to thank Crytek for the Sponza model, Jassim Happa and Vedad Hulusic for their help with the Kiti and the Kalabsha models.  ...

From the Behavior Model of an Animated Visual Language to its Editing Environment Based on Graph Transformation

Torsten Strobl, Mark Minas, Andreas Pleuss, Arnd Vitzthum
2010 Electronic Communications of the EASST  
Animated visual models are a reasonable means for illustrating system behavior. However, implementing animated visual languages and their editing environments is difficult.  ...  These concepts had already been added to Dia-Meta, a framework for generating editing environments, but they provide only low-level support for specifying and implementing animated visual languages; specifying  ...  Using AML and DiaMeta is a promising approach for simplifying the specification effort for complex VLs.  ...

A Novel Lip Synchronization Approach for Games and Virtual Environments

Jan Krejsa Masaryk, Fotis Liarokapis
2021 Zenodo  
This paper presents an algorithm for the offline generation of lip-sync animation. It redefines visemes as sets of constraints on the facial articulators such as lips, jaw, tongue.  ...  The algorithm was comparatively evaluated with 30 healthy participants by presenting a set of phrases delivered verbally by a virtual character.  ...  ACKNOWLEDGMENTS This research was partially supported by the project that has received funding from the European Union's Horizon 2020 Research and Innovation Programme under Grant Agreement No 739578 and  ...

Dissolve detection in abstract video contents

B. Ionescu, C. Vertan, P. Lambert
2011 2011 IEEE International Conference on Acoustics, Speech and Signal Processing (ICASSP)  
We propose a straightforward intensity-based dissolve detection method which is able to cope with the particular constraints of the artistic animated movie domain.  ...  It uses the hypothesis that during a dissolve, the amount of fading-out and fading-in pixels should be high.  ...  The existing approaches can be grouped around several main directions, namely: pixel intensity-based, feature-based, transformed-based and other approaches.  ...

Comparison of Different Types of Visemes using a Constraint-based Coarticulation Model [article]

Oscar M. Martinez Lazalde, Steve Maddock
2010 Computer Graphics and Visual Computing  
In this paper we investigate alternative representations for visemes, produced using motion-captured data, in conjunction with a constraint-based approach for visual speech production.  ...  A common approach to producing visual speech is to interpolate the parameters describing a sequence of mouth shapes, known as visemes, where visemes are the visual counterpart of phonemes.  ...  Finally, section 6 presents conclusions and suggestions for future work. CONSTRAINT-BASED VISUAL SPEECH A posture (viseme) for a phoneme is variable within and between speakers.  ...

A Procedural Approach to Solving Constraints of Articulated Bodies [article]

J. Won Lee, Nakhoon Baek, Dongho Kim, James K. Hahn
2000 Eurographics State of the Art Reports  
This procedural approach can be an alternative to strict physically-based animation methods.  ...  Then the objects are translated and rotated to satisfy the given constraints. Instead of strict simulation of physical laws, we suggest procedural formulations for solving constraints.  ...  The procedural approaches in computer animation are a relatively new and promising area and there are many unsolved problems. We plan to extend the procedural approach to cooperate with collisions.  ...

In this paper, we present a novel facial editing style learning framework that is able to learn a constraint-based Gaussian Process model from a small number of facial-editing pairs, and then it can be  ...  Most of current facial animation editing techniques are frame-based approaches (i.e., manually edit one keyframe every several frames), which is ineffective, time-consuming, and prone to editing inconsistency  ...  Binh Huy Le is supported by a Fellowship from the Vietnam Education Foundation.  ...
