We present an algorithm for multi-person tracking-bydetection
in a particle filtering framework. To address the
unreliability of current state-of-the-art object detectors, our
algorithm tightly couples object detection, classification,
and tracking components. Instead of relying only on the
final, sparse output from a detector, we additionally employ
its continuous intermediate output to impart our approach
with more flexibility to handle difficult situations. The resulting
algorithm robustly tracks a variable number of dynamically
moving persons in complex scenes with occlusions.
The approach does not rely on background modeling
and is based only on 2D information from a single camera,
not requiring any camera or ground plane calibration.
We evaluate the algorithm on the PETS’09 tracking dataset
and discuss the importance of the different algorithm components
to robustly handle difficult situations.
