Subject Style analysis and synthesis in virtual character animations
Abstract The context of my thesis concerns the interaction with virtual worlds and is aimed at applications in the field of digital entertainment. Indeed, this interaction is undergoing major changes due to the growth and ease of accessibility of devices that track 3-dimensional body (depth cameras, accelerometers, etc.). The development of tools for the automatic recognition of a style or an emotion based on a gesture and expression of the face will make it possible to generalize new modes of interaction and new applications. The idea is that the virtual avatar makes the user's emotional state visible through specific gestures and facial expressions. The more realistic this recognition and transfer is, the greater the feeling of immersion will be. In this thesis, our objective is to propose an intuitive approach to capture and to synthesis animations with an emotional state. In order to do this, the first task is to understand "where" the style information is located in an animation. A human knows in a few seconds how to characterize an animation that he sees while the algorithms of recognition and synthesis are still far from it. This study should allow us to propose an approach of automatic characterization of a gesture. In a second step, we will use this taxonomy of style characteristics to propose an approach able to change / edit the style or expression of an animation. For example, we have a character who runs in a "neutral" way, we want to be able to add an expression of anger or sadness recovered in another context. The expected result in this case, is to have the same animation but with an emotion: angry or sad, etc..
