Création de l'espace des expressions faciales à partir de modèles bilinéaires asymétriques

Abstract : This paper analyzes non prototypic expressions. The method is based on an asymmetric bilinear model learned on a small amount of expressions. In the resulting expression space, a blended unknown expression has a signature, that can be interpreted as a mixture of the basic expressions used in the creation of the space. Three methods are compared. Experimental results on the recognition of 14 blended unknown expressions show the relevance of the bilinear models compared to appearance-based methods and the robustness of the person-specific models according to the types of parameters (shape and/or texture).
