This chapter provides an accessible introduction for point processes, and especially Hawkes
processes, for modeling discrete, inter-dependent events over continuous time. We start by …

Today's digital contents are inherently multimedia: text, audio, image, video, and so on.
Video, in particular, has become a new way of communication between Internet users with …

Microphones and cameras have been extensively used to observe and detect human
activity and to facilitate natural modes of interaction between humans and intelligent …

During natural social gatherings, humans tend to organize themselves in the so-called free-
standing conversational groups. In this context, robust head and body pose estimates can …

It is a common experience in our modern world, for us humans to be overwhelmed by the
complexities of technological artifacts around us, and by the attention they demand. While …

Estimating people's head pose is an important problem, for which many solutions have been
proposed. Most existing solutions are based on the use of a single camera and assume that …

Reverberant environments pose a challenge to speech acquisition from distant
microphones. Approaches using microphone arrays have met with limited success. Recent …

Multimedia computing technology, as one of the most effective and pervasive technologies
in modern society, plays irreplaceable roles in bridging user needs with vast amounts of …

This paper presents a novel approach to the problem of determining head pose estimation
and face 3D orientation of several people in low resolution sequences from multiple …

In this paper, we present our system used and evaluated on the CLEAR'07 benchmarks,
both on single-and multi-view head pose estimation. The benchmarks show a high contrast …
