چکیده

This paper introduces a technique for region-based pose tracking without the need to explicitly compute contours. We assume a surface model of a rigid object and at least one calibrated camera view. The goal is to find the pose parameters that optimally fit the model surface to the contour of the object seen in the image. In contrast to conventional contour-based techniques, which acquire the contour to be extracted explicitly from the image, our approach optimizes an energy directly defined on the pose parameters. We show experimental results for rather challenging scenes observed with a monocular and a stereo camera system.

Region Based 3-D Pose Tracking with Occlusions

Despite great progress achieved in 3-D pose tracking during the past years, occlusions and self-occlusions are still an open issue. This is particularly true in silhouette-based tracking where even visible parts cannot be tracked as long as they do not affect the object silhouette. Multiple cameras or motion priors can overcome this problem. However, multiple cameras or appropriate training dat...

Real-Time Monocular Segmentation and Pose Tracking of Multiple Objects

We present a real-time system capable of segmenting multiple 3D objects and tracking their pose using a single RGB camera, based on prior shape knowledge. The proposed method uses twist-coordinates for pose parametrization and a pixel-wise second-order optimization approach which lead to major improvements in terms of tracking robustness, especially in cases of fast motion and scale changes, co...

Model-Free Head Pose Estimation Based on Shape Factorisation and Particle Filtering

Head pose estimation is essential for several applications and is particularly required for head pose-free eye-gaze tracking where estimation of head rotation permits free head movement during tracking. While the literature is broad, the accuracy of recent vision-based head pose estimation methods is contingent upon the availability of training data or accurate initialisation and tracking of sp...

A novel information fusion based FTT algorithm for a driver fatigue monitoring system

This paper presents a novel FTT (Feature Triangle Tracking) algorithm to track the eyes, mouth and pose of a fatigue driver. The proposed method uses the motion information to localize the face region, and the face region is processed in YCrCb color space to determine the locations of the eyes and mouth. According to geometrical relationships of facial components and the varied pose of the driv...

Hybrid Feature and Template Based Tracking for Augmented Reality Application

Visual tracking is the core technology that enables the visionbased augmented reality application. Recent contributions in visual tracking are dominated by template-based tracking approaches such as ESM due to its accuracy in estimating the camera pose. However, it is shown that the template-based tracking approach is less robust against large inter-frames displacements and image variations tha...
