Signal Processing, 2023 This paper addresses the problem of real-time detection and tracking of a non-cooperative target in the challenging scenario with almost no a-priori information about target birth, death, dynamics and detection probability. Furthermore, there are false and missing data at an unknown yet low rate in the measurements.

An efficient real-time target tracking algorithm using adaptive feature fusion [PDF]
Journal of Visual Communication and Image Representation, 103505
(2022), 2022 Visual-based target tracking is easily influenced by multiple factors, such as background clutter, targets fast-moving, illumination variation, object shape change, occlusion, etc. These factors influence the tracking accuracy of a target tracking task.

A Review on Kernel Learning Method of Moving Target Tracking [PDF]
Hangkong bingqi, 2021 The kernel method maps the original spatial data to a high-dimensional Hilbert space by nonlinear mapping and hides the mapping in the linear learner. The kernel function is used to replace the complex inner product operation in high-dimensional space ...

Magnetometers for tracking metallic targets [PDF]
2010 13th International Conference on Information Fusion, 2010 Starting from Maxwell's equations, we derive a sensor model for three-axis magnetometers suitable for localization and tracking applications. The model depends on the relative position between the sensor and the target, and a physical magnetic multipole model of the target.
