To identify people’s faces from various directions, we propose a novel method that distinguishes people using a combination of face direction estimation and face recognition. Both the face direction estimation method and the face recognition method are appearance-based methods that use a linear discriminant analysis on the same features, the Four-Directional Features. Since these methods are co...

The perceived duration of emotional face stimuli strongly depends on the expressed emotion. But, emotional faces also differ regarding a number of other features like gaze, face direction, or sex. Usually, these features have been controlled by only using pictures of female models with straight gaze and face direction. Doi and Shinohara (2009) reported that an overestimation of angry faces coul...

In this paper, we estimate the eye gaze by using the face direction to estimate the object of interest in an extensive area such as an educational display or museum exhibit. However, the direction of the gaze may differ from that of the face. Therefore, our approach was to use a method that utilizes both the face and eye directions to improve the accuracy of our estimation compared to only usin...

Walkthrough systems have hitherto been developed with the ability to produce a virtual display of a person’s field of view. If the actual position and orientation of a person’s face can be ascertained, then walkthrough images could be created to match this person’s face direction, thereby recreating video corresponding to the view from this person’s face direction. A possible application of thi...

We propose a multi-camera system that can detect omni-directional pointing gestures and estimate the direction of pointing. In general, when a human points a t something, their target exists directly in front of the direction they are facing. Therefore, we regard the direction of pointing as the direction represented by the straight line that connects the face position with the hand position. F...
