Head pose estimation without manual initialization
نویسنده
چکیده
This paper describes a fully automatic system for recovering the rigid components of head pose. It follows the conventional approach of tracking pose changes relative to a reference configuration. Rather than being supplied manually, here the reference configuration is determined by directly estimating pose from the image when the head is close to a frontal presentation. Tracking of pose is done in an intermediate coordinate system which minimizes the impact of errors in estimates of the 3D shape of the head being tracked.

Wide-Range, Person- and Illumination-Insensitive Head Orientation Estimation
We present an algorithm for estimation of head orientation, given cropped images of a subject’s head from any viewpoint. Our algorithm handles dramatic changes in illumination, applies to many people without per-user initialization, and covers a wider range (e.g., side and back) of head orientations than previous algorithms. The algorithm builds an ellipsoidal model of the head, where points on...
متن کاملHead Pose Estimation System Based on Particle Filtering with Adaptive Diffusion Control
In this paper, we propose a new tracking system based on a stochastic filtering framework for reliably estimating the 3D pose of a user’s head in real-time. Our system estimates the pose of a user’s head in each image frame whose 3D model is automatically obtained at an initialization step. In particular, our estimation method is designed to control the diffusion factor of a motion model adapti...

Vision-based automatic human body pose estimation has many potential applications and it is also a challenging task. Together, these two factors have made vision-based human body pose estimation an attractive research area with closely related research areas including body pose, hand pose, and head pose estimation. Up to now, these research works however only deal with each task of estimating b...
متن کاملCoarse Head-Orientation Estimation with Bootstrap Initialization
We present an algorithm for estimation of head orientation and describe automated bootstrap initialization of a person-speci c model from a generic model to achieve greater accuracy. Given pose-annotated, cropped images of people's heads from various viewpoints, the algorithm builds an ellipsoidal 3D model of the head, where points on the model learn probabilistic information about local edge d...
متن کاملModel-Based Head Tracking and 3D Pose Estimation
This paper presents a generic method for addressing the issue of 3D model-based head pose estimation. The method proposed relies on the downhill simplex optimization method and on the combination of motion and texture features. A proper initialization based on a block matching procedure associated with 3D/2D matching depending on texture and optical flow information leads to an accurate recover...
