Robust, Real-Time 3D Face Tracking from a Monocular View
This paper addresses the problem of 3D face tracking from a monocular view. Dominant tracking algorithms in current literature can be classified as intensity-based or feature-based methods. Intensity-based methods track 3D faces based on the brightness constraint, assuming constant intensity of the face across adjacent frames. Feature-based trackers use local 2D features to determine sparse pai...
متن کامل3D Face pose estimation and tracking from a monocular camera
In this paper, we describe a new approach for estimating and tracking three-dimensional (3D) pose of a human face from the face images obtained from a single monocular view with full perspective projection. We assume that the shape of a 3D face can be approximated by an ellipse and that the aspect ratio of 3D face ellipse is given. Given a monocular image of a face, we ®rst perform an ellipse d...
متن کاملReal Time 3D Facial Movement Tracking Using a Monocular Camera
The paper proposes a robust framework for 3D facial movement tracking in real time using a monocular camera. It is designed to estimate the 3D face pose and local facial animation such as eyelid movement and mouth movement. The framework firstly utilizes the Discriminative Shape Regression method to locate the facial feature points on the 2D image and fuses the 2D data with a 3D face model usin...
متن کاملRobust Real-Time Multi-View Eye Tracking
Despite significant advances in improving the gaze estimation accuracy under controlled conditions, the tracking robustness under real-world conditions, such as large head pose and movements, use of eye glasses, illumination and eye type variations, remains a major challenge in eye tracking. In this paper, we revisit this challenge and introduce a real-time multi-camera eye tracking framework t...
متن کاملReal- Time Monocular Face Tracking Using an Active Camera
This paper addresses the problem of facial feature detection and tracking in real-time using a single active camera. The variable parameters of the camera (i.e pan, tilt and zoom) are changed adaptively to track the face of the agent in successive frames and detect the facial features which may be used for facial expression analysis for surveillance or mesh generation for animation purposes, at...
