Multi-Target Tracking in Visual Images -- Finding,
Following and Identifying Football Players During a Game
Josephine Sullivan (KTH, Sweden)
Successful multi-target tracking requires solving two problems -
localising the targets and labelling their identity. An
isolated target's identity can be unambiguously preserved from one
frame to the next. However, for long sequences of many moving
targets, like a football game, grouping scenarios will occur in
which identity labellings cannot be maintained reliably by using
continuity of motion or appearance.
In this talk I'll describe how
a graph structure can be built and used to describe the
interactions that occur. Given this platform, I'll present two
separate strategies for labelling the identity of the nodes of this
graph. Results will be shown from an international football match
captured by a multi-camera rig that produces a wide screen video
that is full stationary view of the pitch.
