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.

To address such problems, a divide-and-conquer manner has been employed with parallel computation.

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.

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