Symmetry-based head pose estimation for intention detection
نویسندگان
چکیده
This paper describes a visual interface that infers the intention of a person to travel in a desired direction from head movements. A rotation of the head indicates the intent to change direction. The context for which this solution is intended is that of wheelchair bound individuals. This paper describes work in progress that provides a proof of concept tested on static images where head pose changes can be detected in a sequence of frames and where the pose of an individual is remarkably detected for 30, 60 and 90 angles. Results show that the symmetry property of the head can be used to detect a change in its position and can therefore serve as a visual intent indicator. The solution described in this paper, focusing on the specific task of head pose estimation, intends to provide a contribution to the task of intention detection applied to assistive living for the support of the elderly and people with disabilities.

3D Head Pose Estimation with Symmetry Based Illumination Model in Low Resolution Video
A head pose estimation system is described, which uses low resolution video sequences to determine the orientation and position of a head with respect to a internally calibrated camera. The system employs a feature based approach to roughly estimate the head pose and an approach using a symmetry based illumination model to refine the head pose independent of the users albedo and illumination in...
متن کاملReal-time Head Pose Estimation with Stereo Vision
Head pose estimation is an important task for many applications such as human-computer interaction and human action understanding since a person’s head direction has an important role in representing his/her intention. In this paper, we propose a real-time head pose estimation method with stereo vision, which does not stress users and is easily applied to a lot of users. We use the degree of th...
متن کاملHead Pose Estimation on Top of Haar-Like Face Detection: A Study Using the Kinect Sensor
Head pose estimation is a crucial initial task for human face analysis, which is employed in several computer vision systems, such as: facial expression recognition, head gesture recognition, yawn detection, etc. In this work, we propose a frame-based approach to estimate the head pose on top of the Viola and Jones (VJ) Haar-like face detector. Several appearance and depth-based feature types a...
متن کاملVisual Intention Detection for Wheelchair Motion
This paper describes a visual interface that recognizes the command request of a person by inferring the intention to travel in a desired direction at a certain speed from the person’s head movements. A rotation and a vertical motion indicate the intent to change direction and speed respectively. The context for which this solution is intended is that of wheelchair bound individuals. This paper...
متن کامل3D Head Pose Estimation from Multiple Distant Views
A method for human head pose estimation in multicamera environments is proposed. The method computes the textured visual hull of the subject and unfolds the texture of the head on a hypothetical sphere around it, whose parameterization is iteratively rotated so that the face eventually occurs on its equator. This gives rise to a spherical image, in which face detection is simplified, because ex...
