Bridging Echolocation Gaps in Automated Beaked Whale Tracking
Clair Ma, Thomas Kropfreiter, Lauren Baggett +2
Passive acoustic monitoring (PAM) is an effective and widely used tool for tracking marine mammals, particularly beaked whales, which are infrequently observed visually because of…
Association-Based Track-Before-Detect with Object Contribution Probabilities
Thomas Kropfreiter, Jason L. Williams, Florian Meyer
Multiobject tracking provides situational awareness that enables new applications for modern convenience, applied ocean sciences, public safety, and homeland security. In many mult…
Multiobject Tracking for Thresholded Cell Measurements
Thomas Kropfreiter, Jason L. Williams, Florian Meyer
In many multiobject tracking applications, including radar and sonar tracking, after prefiltering the received signal, measurement data is typically structured in cells. The cells,…
Track Coalescence and Repulsion in Multitarget Tracking: An Analysis of MHT, JPDA, and Belief Propagation Methods
Thomas Kropfreiter, Florian Meyer, David F. Crouse +3
Joint probabilistic data association (JPDA) filter methods and multiple hypothesis tracking (MHT) methods are widely used for multitarget tracking (MTT). However, they are known to…
A BP Method for Track-Before-Detect
Mingchao Liang, Thomas Kropfreiter, Florian Meyer
Tracking an unknown number of low-observable objects is notoriously challenging. This letter proposes a sequential Bayesian estimation method based on the track-before-detect (TBD)…
Track Coalescence and Repulsion: MHT, JPDA, and BP
Thomas Kropfreiter, Florian Meyer, Stefano Coraluppi +3
Joint probabilistic data association (JPDA) and multiple hypothesis tracking (MHT) introduced in the 70s, are still widely used methods for multitarget tracking (MTT). Extensive st…
