In the human quest for scientific knowledge, empirical evidence is
collected by visual perception. Tracking with computer vision takes
on the important role to reveal complex patterns of motion that
exist in the world we live in. Multi-object tracking algorithms
provide new information on how groups and individual group members
move through three-dimensional space. They enable us to study in
depth the relationships between individuals in moving groups. These
may be interactions of pedestrians on a crowded sidewalk, living
cells under a microscope, or bats emerging in large numbers from a
cave. Being able to track pedestrians is important for urban
planning; analysis of cell interactions supports research on
biomaterial design; and the study of bat and bird flight can guide
the engineering of aircraft. We were inspired by this multitude of
applications to consider the crucial component needed to advance a
single-object tracking system to a multi-object tracking
system-data association. Data association in the most general sense
is the process of matching information about newly observed objects
with information that was previously observed about them. This
information may be about their identities, positions, or
trajectories. Algorithms for data association search for matches
that optimize certain match criteria and are subject to physical
conditions. They can therefore be formulated as solving a
"constrained optimization problem"-the problem of optimizing an
objective function of some variables in the presence of constraints
on these variables. As such, data association methods have a strong
mathematical grounding and are valuable general tools for computer
vision researchers. This book serves as a tutorial on data
association methods, intended for both students and experts in
computer vision. We describe the basic research problems, review
the current state of the art, and present some recently developed
approaches. The book covers multi-object tracking in two and three
dimensions. We consider two imaging scenarios involving either
single cameras or multiple cameras with overlapping fields of view,
and requiring across-time and across-view data association methods.
In addition to methods that match new measurements to already
established tracks, we describe methods that match trajectory
segments, also called tracklets. The book presents a principled
application of data association to solve two interesting tasks:
first, analyzing the movements of groups of free-flying animals and
second, reconstructing the movements of groups of pedestrians. We
conclude by discussing exciting directions for future research.
