Efficient Implementations of Extended Object PMBM Filters with Blocked Gibbs Sampling

Yuxuan Xia, Ángel F. García-Fernández, Lennart Svensson

This paper considers multiple extended object tracking based on Poisson multi-Bernoulli mixture (PMBM) filtering, which gives the closed-form Bayesian solution for standard multipl…

Occlusion-Aware Multi-Object Tracking via Expected Probability of Detection

Jan Krejčí, Oliver Kost, Yuxuan Xia +2

This paper addresses multi-object systems, where objects may occlude one another relative to the sensor. The standard point-object model for detection-based sensors is enhanced so…

Model-based Multi-object Visual Tracking: Identification and Standard Model Limitations

Jan Krejčí, Oliver Kost, Yuxuan Xia +2

This paper uses multi-object tracking methods known from the radar tracking community to address the problem of pedestrian tracking using 2D bounding box detections. The standard p…

GOSPA and T-GOSPA quasi-metrics for evaluation of multi-object tracking algorithms

Ángel F. García-Fernández, Jinhao Gu, Lennart Svensson +4

This paper introduces two quasi-metrics for performance assessment of multi-object tracking (MOT) algorithms. One quasi-metric is an extension of the generalised optimal subpattern…

Probabilistic Trajectory GOSPA: A Metric for Uncertainty-Aware Multi-Object Tracking Performance Evaluation

Yuxuan Xia, Ángel F. García-Fernández, Johan Karlsson +3

This paper presents a generalization of the trajectory general optimal sub-pattern assignment (GOSPA) metric for evaluating multi-object tracking algorithms that provide trajectory…

Probabilistic GOSPA: A Metric for Performance Evaluation of Multi-Object Filters with Uncertainties

Yuxuan Xia, Ángel F. García-Fernández, Johan Karlsson +3

This paper presents a probabilistic generalization of the Generalized Optimal Sub-Pattern Assignment (GOSPA) metric, termed P-GOSPA. The GOSPA metric has been widely used to evalua…
