This paper introduces the concept of a mean for trajectories and multi-object trajectories--sets or multi-sets of trajectories--along with algorithms for computing them.

Building on this, we outline the fundamentals of multi-object state space modeling and estimation using LRFS, which formally address object identities/trajectories, ancestries for spawning objects, and characterization of the uncertainty on the ensemble of objects (and their trajectories).

In occlusion handling, the filter's efficacy is dictated by trade-offs between the sophistication of the occlusion model and computational demand.

Specifically, we exploit the 2D detections and extracted features from multiple cameras to provide a better approximation of the multi-object filtering density to realize the track initiation/termination and re-identification functionalities.

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.

This paper examines performance evaluation criteria for basic vision tasks involving sets of objects namely, object detection, instance-level segmentation and multi-object tracking.

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

In the forward filtering stage, we use the GLMB filter to generate a set of labels and the association history between labels and the measurements.
