TDOA-based adaptive observer trajectory optimisation algorithm for tracking in passive coherent location system

The Journal of Engineering, 2019
In the passive coherent location system with fixed observers, the target tracking performance is limited by the inappropriate localisation geometry. This study proposes an adaptive observer trajectory optimisation (AOTO) algorithm in terms of minimising ...

Does Video Compression Impact Tracking Accuracy?

2022 IEEE International Symposium on Circuits and Systems (ISCAS), 2022
Everyone "knows" that compressing a video will degrade the accuracy of object tracking. Yet, a literature search on this topic reveals that there is very little documented evidence for this presumed fact. Part of the reason is that, until recently, there were no object tracking datasets for uncompressed video, which made studying the effects of ...

The Tracking Machine Learning Challenge: Accuracy Phase [PDF]

, 2019
This paper reports the results of an experiment in high energy physics: using the power of the "crowd" to solve difficult experimental problems linked to tracking accurately the trajectory of particles in the Large Hadron Collider (LHC). This experiment took the form of a machine learning challenge organized in 2018: the Tracking Machine Learning ...
