We have been developing a proactive spoken dialog system on a plasma display panel
(PDP).“Proactive dialog system” referes to a system with the added functionality of actively …

This paper presents an approach to increase the robustness of Active Appearance Models
(AAMs) within the scope of human-robot-interaction. Due to unknown environments with …

We proposed a dialog system on Kyoto tourist information assistance in a client-server
fashion. Our proposed system is called the “proactive dialog system” and aims to present …

In this paper, we propose an eye detection method that is adaptive to facial poses, using a
particle filter and gradient directional features. To estimate the boundary between the iris …

This paper presents the results of an evaluation of image-processing techniques for
estimating facial direction from a camera for a multi-modal spoken dialog system on a large …

In this paper, we propose an eye detection method that is robust to facial poses changes
using edge directional features and a particle filter. To estimate the boundary between the …

In this paper, we propose an eye detection method that is adaptive to facial rotation, using a
particle filter and edge directional features. To estimate the boundary between the iris and …

Most recent facial expressions recognition systems only work well with frontal face images.
However, subjects do not always face front. With this in mind, we propose in this paper a …

In this paper, we propose an eye detection method that is robust to facial pose changes
using gradient directional features of brightness and a particle filter. The rejection function of …

This paper introduces a video-based real-time 3D head pose tracking method for analyzing
human interactions. Most of the existing image-based face tracking approaches, such as …
