Spiral visual and motional tracking
Neurocomputing, 2017Constructing a visual appearance model is essential for visual tracking. However, relying only on the visual model during appearance changes is insufficient and may even interfere with achieving good results. Although several visual tracking algorithms emphasize motional tracking that estimates the motion state of the object center between consecutive ...

Monocular human motion tracking
Multimedia Systems, 2004Human motion tracking from monocular image sequences has been explored widely. However, a framework that addresses the variety of sensing conditions is lacking. In this paper, we present a simple, efficient, and robust method for recovering plausible 3D motion from a video without knowledge of the camera's parameters.

Motion tracking of iris features for eye tracking
Proceedings of the 11th ACM Symposium on Eye Tracking Research & Applications, 2019Current video-based eye trackers fail to acquire a high signal-to-noise (SNR) ratio which is crucial for specific applications like interactive systems, event detection, the study of various eye movements, and most importantly estimating the gaze position with high certainty.

Contour tracking with abrupt motion
2009 16th IEEE International Conference on Image Processing (ICIP), 2009Traditional contour tracking methods can not handle abrupt motion or low frame rate video. This is because the basis of the traditional tracking lies in the assumption that the motion is smooth between consecutive frames. However, the abrupt motion destroys the foundation of this assumption.

Stabilizing motion tracking using retrieved motion priors
2009 IEEE 12th International Conference on Computer Vision, 2009In this paper, we introduce a novel iterative motion tracking framework that combines 3D tracking techniques with motion retrieval for stabilizing markerless human motion capturing. The basic idea is to start human tracking without prior knowledge about the performed actions.

Nonlinear Observer for Vehicle Motion Tracking
2018 Annual American Control Conference (ACC), 2018This paper focuses on the development and use of a nonlinear observer for tracking of vehicle motion trajectories on highways while using a radar or laser sensor. Previous results on vehicle tracking have typically used an interacting multiple model filter that needs different models for different modes of vehicle motion.

Motion prediction for tracking the beating heart
2008 30th Annual International Conference of the IEEE Engineering in Medicine and Biology Society, 2008In the past few years, several research groups have worked on the design of efficient motion compensation systems for cardiac robotic-assisted Minimally Invasive Surgery (MIS). By providing surgeons with a stabilized work environment, significant improvements of the precision and repeatability of their gestures can be achieved.

Neural Architectures for Motion Tracking
1993The goal of a visual tracking system is to evaluate the motion parameters of an object in a scene. The present research approaches this problem from a connectionist perspective, aiming at an effective methodology with the fewest assumptions on the observed domain.

We describe a computer system that allows real-time tracking of facial expressions. Sparse, fast visual measurements using 2D templates are used to observe the face of a subject. Rather than track features on the face, the distributed response of a set of templates is used to characterize a given facial region.
