ABSTRACT
We present a real-time multi-object tracker using an enhanced
version of the Gaussian mixture probability hypothesis den-
sity (GM-PHD) filter to track detections of a state-of-the-art
convolutional neural network (CNN). This approach adapts
the GM-PHD filter to a real-world scenario to recover tar-
get trajectories in remote sensing videos. Our GM-PHD filter
uses a measurement-driven birth, considers past tracked ob-
jects, and uses CNN information to propose better hypotheses
initialization. Additionally, we present a label tracking solu-
tion for the GM-PHD filter to improve identity propagation
given target path uncertainties. Our results show competitive
scores against other trackers while obtaining real-time per-
formance.
