Traditional animation of characters relies on the design of an external shape, called the skin,and an internal skeleton, composed of a hierarchy of frames, which enables one to control thedeformation of the skin in a consistent and predictable way. Since it is relatively efficient, thisskinning technique is widely used in computer graphics production environments. However, it<lb...

Et Aveugles En Traitement Du Signal Et Des Images

We consider the problem of subspace estimation in aBayesian setting. Since we are operating in the Grassmann man-ifold, the usual approach which consists of minimizing the meansquare error (MSE) between the true subspace and its estimatemay not be adequate as the MSE is not the natural metric in theGrassmann manifold , i.e., the set of -dimensional subspacesin . As an al...

Simulation de la dynamique des émotions et des relations sociales de personnages virtuels

One of the main challenges faced by the video game industry is to give life to believable Non-Player Characters (NPCs) . Research shows that emotions play a key role in determining the behavior of individuals. In order to improve the believability of NPCs’ behavior, we propose in this article a model of the dynamics of emotions taking into account the personality and the social relations of the...

Traitement des images et radiothérapie Image processing and radiotherapy

Medical images are of great importance in radiotherapy, which became a privileged application field for image processing techniques. Moreover, because of the progression of the computers’ performances, these techniques are also in full expansion. Today, the recent developments of the radiotherapy (3DCR, IMRT) offer a huge place to them. Effectively, they can potentially answer to the precision ...
