This paper considers the fusion of multiple estimates of a spatially extended object, where the object extent is modeled as an ellipse parameterized by the orientation and semi-axes lengths. For this purpose, we propose a novel systematic approach that employs a distance measure for ellipses, i.e., the Gaussian Wasserstein distance, as a cost function. We derive an explicit approximate expression for the Minimum Mean Gaussian Wasserstein distance (MMGW) estimate. Based on the concept of a MMGW…

Fusion of Elliptical Extended Object Estimates Parameterized with Orientation and Axes Lengths
This article introduces a novel Bayesian framework for elliptic extent estimation and fusion based on two new concepts: a probability density function for ellipses called Random Ellipse Density (RED) that incorporates the ambiguities that come with the ellipse parameterization and the Minimum Mean Gaussian Wasserstein (MMGW) estimate, which is optimal with respect to the GaussianWasserstein distance.
Learning-Based Extended Object Tracking Using Hierarchical Truncation Measurement Model With Automotive Radar
This paper presents a data-driven measurement model for extended object tracking (EOT) with automotive radar that is modeled as a hierarchical truncated Gaussian (HTG) with structural geometry parameters that can be learned from the training data.


Tracking the Orientation and Axes Lengths of an Elliptical Extended Object
This study presents compact closed-form expressions for a recursive Kalman filter that explicitly estimates the orientation and axes lengths of an extended object based on detections that are scattered over the object surface (according to a Gaussian distribution).
A Cartesian B-Spline Vehicle Model for Extended Object Tracking
In this paper a novel representation of the contour of an spatially extended object is proposed, which is tailored to vehicles with an unknown size and orientation that are tracked based on
Metrics for performance evaluation of elliptic extended object tracking methods
The Gaussian Wasserstein metric is suggested for comparing elliptic shapes and its advantages are illustrated and the difficulties of selecting a proper metric for this purpose are highlighted.
Shape tracking of extended objects and group targets with star-convex RHMs
In this paper, a star-convex RHM is introduced for tracking star- Convex shape approximations of targets and Bayesian inference is performed by means of a Gaussian-assumed state estimator allowing for an efficient recursive closed-form measurement update.
GM-PHD filter for multiple extended object tracking based on the multiplicative error shape model and network flow labeling
A novel implementation of the Probability Density Hypotheses filter for tracking an unknown number of extended objects and a track labeling method based on a Minimum-Cost flow (MCF) formulation, which is inspired by tracking-by-detection algorithms from computer vision are proposed.
Tracking rectangular and elliptical extended targets using laser measurements
The proposed method can easily be integrated into any tracking framework that relies on the use of an extended Kalman filter, and it is used together with a recently proposed Gaussian mixture probability hypothesis density (GM-PHD) filter for extended target tracking.
The volcanormal density for radar-based extended target tracking
A novel shape model is presented, designed to approximate the radar measurement spread of a vehicle more adequately than widely used models, and a recent Doppler measurement model is integrated in a maximum likelihood estimator.

With simulated sensor data produced by a partly unresolvable aircraft formation the addressed phenomena are illustrated and an approximate Bayesian solution to the resulting tracking problem is proposed.
A Consistent Metric for Performance Evaluation of Multi-Object Filters
This paper outlines the inconsistencies of existing metrics in the context of multi- object miss-distances for performance evaluation, and proposes a new mathematically and intuitively consistent metric that addresses the drawbacks of current multi-object performance evaluation metrics.
