Backtracking: Retrospective multi-target tracking

Computer Vision and Image Understanding, 2012
We introduce a multi-target tracking algorithm that operates on prerecorded video as typically found in post-incident surveillance camera investigation. Apart from being robust to visual challenges such as occlusion and variation in camera view, our algorithm is also robust to temporal challenges, in particular unknown variation in frame rate.

Performance Measures and a Data Set for Multi-target, Multi-camera Tracking

ECCV Workshops, 2016
To help accelerate progress in multi-target, multi-camera tracking systems, we present (i) a new pair of precision-recall measures of performance that treats errors of all types uniformly and emphasizes correct identification over sources of error; (ii ...

Subgraph decomposition for multi-target tracking

2015 IEEE Conference on Computer Vision and Pattern Recognition (CVPR), 2015
Tracking multiple targets in a video, based on a finite set of detection hypotheses, is a persistent problem in computer vision. A common strategy for tracking is to first select hypotheses spatially and then to link these over time while maintaining disjoint path constraints [14, 15, 24].

Multi-target tracking using passive Doppler measurements

2013 21st Signal Processing and Communications Applications Conference (SIU), 2013
In this paper, we analyze the performance of the Gaussian mixture probability hypothesis density (GM-PHD) filter in tracking multiple non-cooperative targets using Doppler-only measurements in a passive sensor network. Clutter, missed detections and multi-static Doppler variances are incorporated into a realistic multi-target scenario.

Pose-Based Multi-Target Tracking

2019 IEEE International Conferences on Ubiquitous Computing & Communications (IUCC) and Data Science and Computational Intelligence (DSCI) and Smart Computing, Networking and Services (SmartCNS), 2019
Human multi-target tracking in video is an important issue in the field of computer vision. It is necessary to detect the target on each frame, and to connect the targets of all frames into a target sequence. For target matching among different frames, we propose a tracking algorithm for constructing object pose sequence(COPS) based on Openpose.

Multi-target tracking by detection

2016 International Conference on Audio, Language and Image Processing (ICALIP), 2016
Aiming at the problem how to express relevant relationship between multiple targets, we propose an approach based on the tracking-by-detection (TBD) strategy, where detections from the HOG classifier are regarded as image evidence. Focusing on the issue of localization uncertainty, data association based on greedy heuristics is executed iteratively to ...

Signature-driven multi-target tracking

2010 13th International Conference on Information Fusion, 2010
Tracking multiple maneuvering targets remains a challenge because of clutter and spurious targets. We propose a Signature-Driven multiple target Tracking (SDT) method which fuses target data in spectral, spatial and temporary spaces to form signatures of targets.

Low Probability of Intercept-Based Collaborative Power and Bandwidth Allocation Strategy for Multi-Target Tracking in Distributed Radar Network System

IEEE Sensors Journal, 2020
In order to simultaneously enhance the low probability of intercept (LPI) performance and resource utilization of distributed radar network system, an LPI-based collaborative power and bandwidth allocation (CPBA) strategy is developed for multi-target ...

A Multi Target Track Before Detect Application

2003 Conference on Computer Vision and Pattern Recognition Workshop, 2003
This paper deals with a radar track before detect application in a multi target setting. Track before detect is a method to track weak objects (targets) on the basis raw radar measurements, e.g. the reflected target power. In classical target tracking, the tracking process is performed on the basis of pre-processed measurements, that are constructed ...
