Realistic facial expression animation requires a powerful “animator”(or graphics program)
that can represent the kinds of variations in facial appearance that are both possible and …

This paper presents a unified approach to solve different bilinear factorization problems in
computer vision in the presence of missing data in the measurements. The problem is …

The synthesis of facial expressions has applicationsin areas such as interactive games,
biometrics systems, and training of people with disorders, among others. Although this is an …

Face modeling refers to modeling the shape and appearance of human faces which lays the
basis for model-based facial analysis, synthesis and animation. This paper summarizes the …

This study presents a facial expression recognition system which separates the non-rigid
facial expression from the rigid head rotation and estimates the 3D rigid head rotation angle …

In human–computer interaction, there is a need for computer to recognize human facial
expression accurately. This paper proposes a novel and effective approach for facial …

In this work we describe the usage of bilinear statistical models as a means of factoring the
shape variability into two components attributed to inter-subject variation and to the intrinsic …

Over the last decades, expression classification and face recognition have received
substantial attention in computer vision and pattern recognition with more recent efforts …

Appearance Models have been applied to model the space of human faces over the last two
decades. In particular, Active Appearance Models (AAMs) have been successfully used for …

Facial images change appearance due to multiple factors such as different poses, lighting
variations, and facial expressions. Tensors are higher order extensions of vectors and …
