Abstract
This paper presents a novel approach for tracking hu-
mans and objects under severe occlusion. We intro-
duce a new paradigm for multiple hypotheses tracking,
observe-and-explain, as opposed to the previous paradigm
of hypothesize-and-test. Our approach efficiently enumer-
ates multiple possibilities of tracking by generating several
likely `explanations' after concatenating a sufficient amount
of observations. The computational advantages of our ap-
proach over the previous paradigm under severe occlusions
are presented. The tracking system is implemented and
tested using the i-Lids dataset, which consists of videos of
humans and objects moving in a London subway station.
The experimental results show that our new approach is
