The Smooth Trajectory Estimator for LMB Filters

no code implementations1 Jan 2024 Hoa Van Nguyen, Tran Thien Dat Nguyen, Changbeom Shim, Marzhar Anuar

In particular, we construct a smooth-trajectory estimator (i. e., an estimator over the entire trajectories of labelled estimates) for the LMB filter based on the history of the best association map and all of the measurements up to the current time.

Linear Complexity Gibbs Sampling for Generalized Labeled Multi-Bernoulli Filtering

no code implementations29 Nov 2022 Changbeom Shim, Ba-Tuong Vo, Ba-Ngu Vo, Jonah Ong, Diluka Moratuwage

Specifically, we propose a tempered Gibbs sampler that exploits the structure of the GLMB filtering density to achieve an $\mathcal{O}(T(P+M))$ complexity, where $T$ is the number of iterations of the algorithm, $P$ and $M$ are the number hypothesized objects and measurements.

Multi-object Tracking with an Adaptive Generalized Labeled Multi-Bernoulli Filter

1 code implementation2 Aug 2020 Cong-Thanh Do, Tran Thien Dat Nguyen, Diluka Moratuwage, Changbeom Shim, Yon Dohn Chung

The challenges in multi-object tracking mainly stem from the random variations in the cardinality and states of objects during the tracking process.
