Abstract:
We propose a data-driven approach to online
multi-object tracking (MOT) that uses a convolutional neural
network (CNN) for data association in a tracking-by-detection
framework. The problem of multi-target tracking aims to assign
noisy detections to a-priori unknown and time-varying number
of tracked objects across a sequence of frames. A majority
of the existing solutions focus on either tediously designing
cost functions or formulating the task of data association as
a complex optimization problem that can be solved effectively.
Instead, we exploit the power of deep learning to formulate the
data association problem as inference in a CNN. To this end, we
propose to learn a similarity function that combines cues from
both image and spatial features of objects. Our solution learns
to perform global assignments in 3D purely from data, handles
noisy detections and a varying number of targets, and is easy
to train. We evaluate our approach on the challenging KITTI
dataset and show competitive results. Our code is available at
