This paper describes a novel approach to building models of temporal dynamics for facial
animation with applications in performing perceptual testing of trustworthiness. A vital …

This paper describes a system for tracking a face and its facial features in an input video
sequence using the active appearance algorithm. The algorithm adapts a wireframe model …

Facial motions produce not only facial feature points motions, but also subtle appearance
changes such as wrinkles and shading changes. These subtle changes are important yet …

We wish to model the way in which faces move in video sequences. We represent facial
behaviour as a sequence of short actions. Each action is a sample from a statistical model …

In this work, we address a method that is able to track simultaneously 3D head movements
and facial actions like lip and eyebrow movements in a video sequence. In a baseline …

We present a technique for reconstructing facial movies, given a small number of real
images and a few parameters for the in-between images. The parameters can be …

We describe a computer system that allows real-time tracking of facial expressions. Sparse,
fast visual measurements using 2D templates are used to observe the face of a subject …

The tracking of facial activities from video is an important and challenging problem.
Nowadays, many computer vision techniques have been proposed to characterize the facial …

When estimating the dense motion field of a video sequence, if little is known or assumed
about the content, a limited constraint approach such as optical flow must be used. Since …

Temporal segmentation of facial gestures in spontaneous facial behavior recorded in real-
world settings is an important, unsolved, and relatively unexplored problem in facial image …
