As one of the most successful applications of image analysis and understanding, face
recognition has recently received significant attention, especially during the past several …

Video analysis of human dynamics is an important area of research devoted to detecting
people and understanding their dynamic physical behavior in a complex environment that …

We propose a general framework for object tracking in video images. It consists of low-order
parametric models for the image motion of a target region. These models are used to predict …

This paper deals with the low-level joint processing of color and motion for robust face
analysis within a feature-based approach. To gain robustness and contrast under …

The active appearance models (AAMs) provide the detailed descriptive parameters that are
useful for various autonomous face analysis problems. However, they are not suitable for …

In this thesis, we develop computational tools for analyzing conversations based on
nonverbal auditory cues. We develop a notion of conversations as being made up of a …

In recent years, perceptual interfaces have emerged as an increasingly important research
direction. The general focus of this area is to integrate multiple perceptual modalities (such …

Current user interfaces are unsuited to harness the full power of computers. Mobile devices
like cell phones and technologies such as virtual reality demand a richer set of interaction …

Statistical pattern recognition and computer vision techniques have been successfully
applied to many object recognition problems. One typical example is the task of face …

MPEG-4 standard allows composition of natural or synthetic video with facial animation.
Based on this standard, an animated face can be inserted into natural or synthetic video to …
